If thread A forks a child, and thread B does PTRACE_ATTACH to that child, then on death there is one report "to B" (but available to all threads in the same process calling wait*) and then there is a second one "to A". The second one happens because you are the real parent of the child that is no longer ptrace'd after the ptracer's wait returns WIFSIGNALED/WIFEXITED. The first one happens because you are the ptracer but not the real parent, but there are two of you so all things can be true and false. -- http://sourceware.org/bugzilla/show_bug.cgi?id=3639 ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee.
