Hi,

Can anyone help me with this problem?

This happens only on Linux Redhat 3. When I need to terminate a thread
by using pthread_cancel(), I got this core dump. The bug trace follows:


#0  0xb75ebc32 in _dl_sysinfo_int80 () from /lib/ld-linux.so.2
#1  0xb718fa09 in raise () from /lib/tls/libc.so.6

Previous frame inner to this frame (corrupt stack?)


I've searched on web and it seems to be the Bugzilla Bug 104689.
However, the solution suggested (using LD_ASSUME_KERNEL solution)
doesn't work for me.

Does anyone have better solution so that I can cancel the thread
gracefully?

Thanks a lot,
Jessie
