--- Comment #9 from Janne Blomqvist <jb at gcc dot gnu.org> --- Author: jb Date: Sun May 19 19:38:11 2019 New Revision: 271384 URL: https://gcc.gnu.org/viewcvs?rev=271384&root=gcc&view=rev Log: libfortran/90038 Reap dead children when wait=.false. When using posix_spawn or fork to launch a child process, the parent needs to wait for the child, otherwise the dead child is left as a zombie process. For this purpose one can install a signal handler for SIGCHLD. 2019-05-19 Janne Blomqvist <j...@gcc.gnu.org> PR libfortran/90038 * intrinsics/execute_command_line (sigchld_handler): New function.
