It seems a bug in gdb. When multi-thread application being debbuged, the debugger hangs up. The example of code and gdb diagnostics follows.
====================================================
#include <pthread.h>
void *f1(void *arg )
{
}
main()
{
pthread_t thread;
pthread_create(&thread, NULL, &f1, NULL);
return 0;
}
