Hello,
One of our Customer is getting Coredump when our application is trying to load a library(one of our products library) using dlopen() on AIX 6.1.

Our application and our shared library are built on AIX 5.3 machine using xlC compiler.

we have tried executing the same application on our in-house AIX 6.1 machine and we didn't get any issues . Everything working fine.

Problem is with the Customer's Environment.
Customer OSlevel is 6100-02
Here is the stack trace. It shows, core dump occured in __Init().

(dbx)
we have used dlopen as
dlopen(ourlibrary,RTLD_GLOBAL | RTLD_LAZY);

Could you let me know what could be the problem.
Is this a know issue OR Customer Machine is missing any filesets.
Thanks in advance.
