I found "pthread_attr_t attr" was declared as global like "static pthread_attr_t attr", I moved this to locally as "pthread_attr_t attr", then I compiled and try to run, this time when I run with gdb, it terminated by SIGKILL:

I got your link, any work around for this?. I am thinking some issue with my ported code from windows.

[tvnaidu]

if I run my app without GDB, also it gets "Killed", that is why I am running with GDB to see what is happening, anyway can I debug my app?.

seems like pthread library is not getting linked properly...
Can you try running that on other machine? Or may be reinstalling the pthread..
Also, see if there is any LD_ASSUME_KERNEL environment variable set....
