Hi Martin,
Our investigation determined this is not a compiler issue.
The problem is you used a C compiler (xlc) to compile and link a C++
program. The C compiler will not link in the necessary C++ components such
as C++ libraries.
When using the '-q64' option with xlc, the default '-lgcc_eh' library gets
invoked at link time instead of the desired '-lgcc_s_64' library. Hence
the 'segmentation fault' at execution time.
The best solution is to use xlc++ when compiling C++ programs since we
support linking C++ objects with xlc++.
Please contact me if you have any questions regarding this issue.
Sincerely,
Basil Kanneth

Hi Martin,
I would like to inform you that a defect has been opened for this PMR for
XL C/C++ Advanced Edition V8.0 for Linux.
>From my investigation, it appears to be the '-q64' option that causes the
abnormal exit of code on execution.
I am further investigating on why the '-q64' option causes the problem. I
will provide you with an update by Wednesday, June 14th, 2006.
Please feel free to contact me if you have any questions.
Sincerely,
Basil Kanneth
