The problem is the SIGCHLD handler being set to SIG_IGN, which is different from the signal mask. > Can you give some more context when this problem comes up?

However in general terms a trivial plugin which just does: #include <guestfs.h> ... guestfs_h *g; if ((g = guestfs_create ()) == NULL || guestfs_launch (g) == -1) exit (1); should be sufficient to demonstrate the problem. (Work around it by adding ‘signal (SIGCHLD, SIG_DFL);’ to the plugin code.)
