[Bug c++/32288] New: Our C++ program (gcc 4.1.1 under Aix 5.3) crashes with a core dump

[alessandro dot mei at elsagdatamat dot com]

Our C++ program compiled with gcc 4.1.1 on Aix 5.3 terminates abnormally with a
core dump. 
This happens in the initialization phase of the program. The program is the
core process of our application.
We can reproduce it at will. 
This problem occurs with a binary compiled in the production environment.
If we run the binary compiled in the test environment, we have no problem, both
in the production server and in the test one.
Moreover, the program crash is not occuring if we use a higher tracing level.
The production server has an Aix patch set newer than the test server; however
the servers have same version and maintanance level of the operating system,
namely:
production server       Aix V5.3.0.0-05-05
test server     Aix V5.3.0.0-05

•       the exact version of GCC; 
•       the system type; 
•       the options given when GCC was configured/built;

gcc -v
Using built-in specs.
Target: powerpc-ibm-aix5.3.0.0
Configured with: ../gcc-4.1.1/configure --disable-nls
Thread model: aix
gcc version 4.1.1

And why do you think GCC is at fault?  It is hard to debug this huge sources
really.  Have you tried to pin point exactly where the issue.  Do you have any
uninitialized variables?  Are you going over array bounds?  Do you take an
address of a local variable and keep it around even after it goes out of scope?

We have tried to pin point exactly where the crash occurs.
It is hard to debug the source really, we agree, however there is nothing
strange at that line and that code works fine on the test server.
We are using GCC 4.1.1 downloaded from aixpdslib UCLA ftp website.
We suspect that the GCC binary downloaded from this ftp site had been compiled
on an AIX 5.3 version different from the one we are using in the production
server. 
So we are now asking support if our suspect could explain the crash.

No activity for month.  Please re-open if there is more information.  Please
also use a newer 4.1 release such as 4.1.2 or even a release that is still
supported such as 4.2.2.
