@James: In theory it should be, but that code is from 2 different
branches - and you may well be seeing a different issue. Please report a
new bug.

  [Impact]
  After upgrading gdb from 8.1-0ubuntu3 to 8.1-0ubuntu3.1, gdb does not stop
  on breakpoint when running a 32-bit application (on 64-bit Ubuntu).

  [Test Case]
  This can be reproduced with a simple “hello world” program:

  $ cat hello.c
  #include 
  int main()
  {
     // printf() displays the string inside quotation
     printf("Hello, World!");
     return 0;
  }
  $ gcc -ggdb -m32 hello.c
  $ gdb a.out
  (gdb) b hello.c:5
  Breakpoint 1 at 0x536: file hello.c, line 5.
  (gdb) run

  [Regression Risk]
  Test case ran on arm64 and regression tested using the above test case on 
amd64, i386 and s390x.

  This regression was fixed on the upstream gdb-8.1 branch within a few
  weeks of the breakage back in May 2018. Since then there have been no
  other fixes in this area on that branch, implying this fixed the issue
  and there were no further regressions discovered.

Will this have been fixed in "GNU gdb (Ubuntu 9.2-0ubuntu1~20.04) 9.2"?
I'm having similar problems and came across this report claiming that it
is fixed in "8.1-0ubuntu3.2". I don't understand how the numbers work
but assume that 9.2 has fixes that were in 8.1. If not, then that would
explain my problem.

*** This bug is a duplicate of bug 1846557 ***
https://bugs.launchpad.net/bugs/1846557

Thanks Miroslav for opening this bug, two weeks after me opening bug #1846557. 
Unfortunately, it took proving that gdb couldn't debug properly _any_ 32-bit 
program, not just kernels running on QEMU, in order to get some attention. 
Honestly, I didn't even thought the bug could be _that_ bad and I didn't test 
that simple scenario. I just assumed it worked.

But, certainly, just a simple question from any maintainer about this
use-case could have helped solving this bug much earlier and saving time
to all the people it affected. I mean, it's not disappointing that it
took one month to get a fix. If the bug affected only my scenario that
would had been fine. It's disappointing that even if there was a single
_small_ 100% guilty patch, in one month, bug #1846557 did not get a
_single_ technical comment/question. We could have discovered this
broader-scope bug much earlier. It's not about fixing any bug "right
now" (bugs have priority). It's about at least talking with the reporter
and don't underestimate the scope of the bug, even if it appears to be
narrow. It might not be.

I’ve tested version 8.1-0ubuntu3.2 from ubuntu-proposed on my Xubuntu
18.04.3 x86_64 from both the command line and Qt Creator and the problem
has not appeared.

I am also setting verification-done because no other supported releases
seem affected.

[Touch-packages] [Bug 1848200] Re: gdb not stopping on breakpoint in a 32-bit program

[Robie Basak]

Hello Miroslav, or anyone else affected,

Accepted gdb into bionic-proposed. The package will build now and be
available at https://launchpad.net/ubuntu/+source/gdb/8.1-0ubuntu3.2 in
a few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested and change the tag from
verification-needed-bionic to verification-done-bionic. If it does not
fix the bug for you, please add a comment stating that, and change the
tag to verification-failed-bionic. In either case, details of your
testing will help us make a better decision.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!

  [Impact]
  After upgrading gdb from 8.1-0ubuntu3 to 8.1-0ubuntu3.1, gdb does not stop
  on breakpoint when running a 32-bit application (on 64-bit Ubuntu).

  [Test Case]
  This can be reproduced with a simple “hello world” program:

  $ cat hello.c
  #include 
  int main()
  {
     // printf() displays the string inside quotation
     printf("Hello, World!");
     return 0;
  }
  $ gcc -ggdb -m32 hello.c
  $ gdb a.out
  (gdb) b hello.c:5
  Breakpoint 1 at 0x536: file hello.c, line 5.
  (gdb) run
  Starting program: /home/user/sandbox/a.out

  [Regression Risk]
  Test case ran on arm64 and regression tested using the above test case on 
amd64, i386 and s390x.

  This regression was fixed on the upstream gdb-8.1 branch within a few
  weeks of the breakage back in May 2018. Since then there have been no
  other fixes in this area on that branch, implying this fixed the issue
  and there were no further regressions discovered.

  [Impact]
  After upgrading gdb from 8.1-0ubuntu3 to 8.1-0ubuntu3.1, gdb does not stop 
  on breakpoint when running a 32-bit application (on 64-bit Ubuntu). 

  [Test Case]
  This can be reproduced with a simple “hello world” program:

  $ cat hello.c
  #include 
  int main()
  {
     // printf() displays the string inside quotation
     printf("Hello, World!");
     return 0;
  }
  $ gcc -ggdb -m32 hello.c
  $ gdb a.out
  (gdb) b hello.c:5
  Breakpoint 1 at 0x536: file hello.c, line 5.
  (gdb) run
  Starting program: /home/user/sandbox/a.out
  warning: Breakpoint address adjusted from 0xf7fd9be0 to 0xf7fd9be0.
  warning: Breakpoint address adjusted from 0xf7fda195 to 0xf7fda195.
  warning: Breakpoint address adjusted from 0xf7fdbd1c to 0xf7fdbd1c.
  warning: Breakpoint address adjusted from 0xf7fdb924 to 0xf7fdb924.
  warning: Breakpoint address adjusted from 0xf7fe99b3 to 0xf7fe99b3.
  warning: Breakpoint address adjusted from 0xf7fea401 to 0xf7fea401.
  warning: Breakpoint address adjusted from 0xf7fea706 to 0xf7fea706.

  --- (and not stopping nor outputting the text…) ---

  [Regression Risk]
  Test case ran on arm64 and regression tested on amd64/i386.

  This regression was fixed on the upstream gdb-8.1 branch within a few
  weeks of the breakage back in May 2018. Since then there have been no
  other fixes in this area on that branch, implying this fixed the issue
  and there were no further regressions discovered.

  It works well with a 64-bit build (leaving out the gcc’s -m32 option).
