Hi,

Guys I am stuck with a problem and need some help.

Platform     : Linux(RedHat 7.3)
Problem Area : Dynamic Shared Object Libraries, POSIX Threads
glibc        : 2.96

Problem:
=======
The Scenario is such that I have made a module which call a .so file
in a new thread and executes it. The .so file has to be provided by
the end-user and if that .so gives any runtime-error(SEGFAULTS), the
whole process terminates i.e. all the threads executing .so files and
more importantly my .so-calling module, which I dont want to be
terminated.

so ***IS THERE ANY WAY THAT MY SO-CALLING MODULE DOES NOT TERMINATE
DUE TO SOME SEGFAULTS IN A .SO FILE WRITTEN BY THE END-USER OF MY
MODULE?***.

Any relevant comment will be appreciated.

Best Regards,

Nabeel Shaheen
