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.
