| While installing Python 2.7.3 on my Ubuntu server the configure script hanged on the verification for pthread, I then proceded to alter the script to aways return true for pthread and it hanged again checking for PTHREAD_SCOPE_SYSTEM, which I also bypassed by altering the script and only then was I able to successfully install Python 2.7.3 |

| Could you please run: $ sh -x ./configure to see what's going on. It might also be interesting to have the output of $ strace -f ./configure Thanks. |

| Your strace output looks strange :-) Unless it's truncated, we see that the wait4() doesn't return when the test pthread executable exits... Could you try building this code : """ #include <pthread.h> void* routine(void* p){return NULL;} int main(){ pthread_t p; if(pthread_create(&p,NULL,routine,NULL)!=0) return 1; (void)pthread_detach(p); return 0; } """ (with gcc -o test test.c -lpthread) And running it from the command line, to see your shell hangs (you might also want to try 'strace -f sh -c "test"'). |

| Yes, this code is hanging in my system. I'm posting the strace output. If there's any other information that may be helpful I'll happily provide it. |

Well, in that case it's a bug in your pthread implementation: returning from main() with detached threads should terminate the process. You should report this to your distribution bug tracker. |

| I'm closing as invalid. If you decide to fill a bug report to your distribution (or directly to the libc in this case), it'd be interesting to post a link to the bug report here. Thanks. |
