I am not able to catch the failure in gdb because it happens in the child process.
GDB can follow fork(), see
(gdb) help set follow-fork-mode Set debugger response to a program call of fork or vfork. A fork or vfork creates a new process. follow-fork-mode can be: parent - the original process is debugged after a fork child - the new process is debugged after a fork The unfollowed process will continue to run. By default, the debugger will follow the parent process.
