Also can you give me a kind of gcc supported version life cycle/chart/roadmap ?
Thank you,

Hello,
We have a program myapp build with gcc 4.6.3 on AIX 6.1 Tl05.
At runtime the program crashed once very weird with the following stack:
pth_signal.pthread_kill(??, ??) at 0xd053c8d4
pth_signal._p_raise

OK I finally managed to get it working.
The problem was I was using the rpm packages from perlz.org for mpfr,gmp and
libmpc. Both gmp 4.3.2 and 5.0 gave me

One more question:
If I intend to use the patch from PR 33704 to modify my gcc and then build
commercial applications with it, is that ok? Would that raise

I am trying to build gcc 4.7.2 in order to apply the patch you suggested.
I did the following:
-download the gcc 4.7.2
-unzip and untar to to the root

I did not put the patch yet.
This is just gcc 4.7.2 original sources. Why would they not compile?

Finally I got it working. You are right, there are _GLOBAL* symbols generated
for each constructor, but only when you specify the init_priority attr

Follow up on comment 17:
1) I did try to set the priority on the shared lib (via -binitfini) and it does
not work. I mean the priority is set

Regarding the __attribute__ ((init_priority ())).
Are you sure this works on AIX at namespace level. I think it might work on
linux. But on AIX I see

This is a follow up on comment 14.
It seems that -fPIC dramatically improved the way constructors are called. It
seems that the linker has some logic

I found the real problem !
Now it can be reproducible even with a small test case.
I can summarize it like this: If you have a global object/function

(In reply to comment #11)
I believe that the G++ front end tries to create a unique name from the first
symbol it sees. I do not now if this is related
