Oh, and could I ask you for an additional favor? Could please add the attached
patch to add platform support for Linux/m68k? I would highly appreciate that!

Thanks,
Adrian

Alright, thanks.

Btw, my patch might actually fix mips64el as well, see [1].

Well, currently, powerpc is still a release architecture, so I set the severity
accordingly. Also, I'm quite confident that mips64el is failing because of the
same problem.

I found the issue :), see below.

It has to be added to the script template in build/posix/vers.sh.in. I'm
attaching a complete debdiff which fixes the issue for me in powerpc. I
have also opened two PRs upstream, these also include patches for m68k
and an additional patch.

Cheers,
Adrian

Shouldn't this be important instead? According to 
https://release.debian.org/stretch/arch_qualify.html powerpc is not 
a release candidate.

Of course, I am eager to find solution to the crash regardless, just 
arguing about it affecting the potential migration of firebird3.0 to 
testing.

Hmm. I have seen this on amd64 when gcc switched to version 6. Getting 
it built required adding -std=gnu++98 -fno-lifetime-dse 
-fno-delete-null-pointer-checks -fno-strict-aliasing to the compiler 
flags. Probably unrelated.

This is interesting. I was trying to debug a similar issue today on 
the mips64el porterbox. One of the command-line utilities of firebird 
produces garbage upon exit breaking a database verification at the end 
of the build process. (Build log: 
https://buildd.debian.org/status/fetch.php?pkg=firebird3.0=mips64el=3.0.1.32609.ds4-6=1476281685)
There is random garbage emitted by the firebird source preprocessor 
(gpre) which is visible earlier in the build log.
Alpha is also affected.

Where did you add that _IO_stdin_used entry? There are several *.vers 
files in the source. I'll try with all of them and also 
_IO_std{err,out}_used.

(15 minutes later) Oh, it helps! The invocations of gpre no longer 
dump sources. Let's see how far this goes.

Ok, turns out the second crash affects Firebird from git/master only. The patch
above really fixes the problem for the firebird3.0 package in Debian :).

Will prepare a patch shortly and follow up. This *might* also fix the
testsuite failure on mips64el as it apparently also has problems when
_IO_stdin_used is missing.

Ok, the following patch fixes the crash above:

However, it crashes still when running isql during build:

I have done some debugging and from the backtrace it's obvious that
the crash occurs in glibc:

This looks similar to the FTBFS of lua5.3 on powerpc [1] which is
triggered by the use of a version script for the linker and, in
fact, firebird3.0 is using such scripts. Now, this actually reminded
me of another similar problem we had on sparc back then [2] which
is the missing _IO_stdin_used symbol in the version script. lua5.2
was affected by that problem as well and Aurelien Jarno fixed that
by adding that symbol to the version script [3].

I tried the fix from [3] in firebird3.0, but unfortunately it
doesn't help. Currently, I'm out of ideas but it would be great
to see this fixed as this also affects m68k for which I have
added platform support to firebird upstream [4,5].

Thanks,

Adrian
