Charles-Francois Natali <neolo...@free.fr> added the comment: If test_wait3 and test_fork1 pass, then yes, it's probably an issue with AIX's wait4. See http://fixunix.com/aix/84872-sigchld-recursion.html:
""" Replace the wait4() call with a waitpid() call... ....like this: for(n=0;waitpid(-1, &status, WNOHANG) > 0; n++) ; Or, compile the existing code with the BSD library: cc -o demo demo.c -D_BSD -lbsd Both will work... The current problem is that child process is not "seen" by the wait4() call, so that when "signal" is rearmed, it immediately goes (recursively) into the child_handler() function. """ So it seems that under AIX, posix_wait4 should be compiled with -D_BSD -lbsd. Could you try this ? If this doesn't do the trick, then avoiding passing WNOHANG could be the second option. ---------- nosy: +neologix _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue11185> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
