From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.3) Gecko/20041020 Description of problem: Debugging a threaded program with gdb 6.1post-1.20040607.43 and kernel 2.6.10-1.741_FC3smp results in a gdb lockup. At this point if you kill -9 gdb, then the process that you were debugging becomes an unkillable zombie. The process is inherited by by init - it just won't die despite a kill -9. Not using NPTL (via LD_ASSUME_KERNEL=2.2.5 or -rpath to force the older linuxthreads) makes the problem go away. I have tried this with 2.6.9-1.667 and 2.6.10-1.741_FC3 both with and without smp with the same results.
