bug in gdb

[Rustam]

When debugging multithreaded C program that uses pthreads gdb fails.


My system is:

Linux mandrake 9.1
2.4.21-0.18mdk
glibc-2.3.1
GNU gdb 5.3-22mdk (Mandrake Linux)
gcc-3.2.2-3mdk
comiler flags: -Wall -g -O0

It seems gdb fails when my program works with mutexes: locking or unlocking.
