Usually using a Linux distribution, one can easily install debug information
for libraries. You should somehow investigate how is that

I ran the below command to check memory usage. After an initial quick increase
it doesn't seem to grow much.
$ while true; sleep 1; do ps -p $(pgrep -fl ./a.out | awk '{ print $1 }') -o
pmem,rss,vsize,pid; done

Thanks for all your help, Martin, I really appreciate.
I re-ran with ASAN_OPTIONS as you suggested. The program seems to get killed
after about 44 seconds.
I already tried with clang before, seems to work ok over

I'm sorry I cannot help more as I don't have a handy Mac operating system. I
would also try to use clang with the sanitizer and test it. Moreover, you can
test following:
$ gcc /tmp/main.c

Doesn't seem to work, it cannot find the symbol.
(gdb) break __asan_init
Function "__asan_init" not defined.
Make breakpoint pending on future shared library load? (y or [n]) y

--- Comment #10 from Martin Liška ---
Huh, no debugging symbols so hard to guess where lead all the jumps. I would
try to add breakpoint to '__asan_init'.

Ok, I've done that now. Thanks again.

Ok, we're not searching for main function, but _GLOBAL__sub_I_00099_1_m.cpp
(which is a static constructor) and I'm interested in instructions in the
function. Please use gdb once more time, go to frame (#14)

I compiled with -S and looked at m.s.
I'm not sure, but my main function could be this (I found this code in m.s, by
searching for 'main', lines 4058 - 4095):
lC6:
.ascii "foo test 123\0"
.space 51

I installed gdb with homebrew. I think it was compiled with debugging symbols,
because of:
$ otool -Iv /usr/local/opt/gdb/bin/gdb | head -5
/usr/local/opt/gdb/bin/gdb:
Indirect symbols for (__TEXT,__stubs) 452

My constructor for main looks as follows:
_GLOBAL__sub_I_00099_1_main:
.LFB7137:
.cfi_startproc
pushq %rbp
.cfi_def_cfa_offset 16
.cfi_offset 6, -16

I managed to code-sign gdb by following

Not that I expect it to matter much related to this ticket, but I also noticed
the stacktrace looks a little different when I

Read somewhere that I need to do this to make gdb work on Sierra. Not sure what
it all means...
$ cat ~/.gdbinit
set startup-with-shell off
After doing that, I get a different result running gdb.
$ sudo

Thanks Martin. I tried to run it with gdb.
With gdb, I seem to get an unknown signal immediately.
(running gdb as root at the moment, because of an issue with code-signing)
