There is one issue in your code; you shouldn't be calling
waitpid(-1, ...).  That would break any GChildWatchSource watches that
exist in the process.  Instead, use waitpid(pid, ...).

That's not the bug though, assuming that as you say you're just
using g_spawn_async().

The bug is likely to be in kernel/libc then.  Though bisecting[1]
through GLib would help you narrow down what change caused it.
