The way this is supposed to work is that sigchld_handler is not
supposed to call malloc.  However, it was changed to call
strsignal, and that calls malloc.

I think the best fix is to bring it back to the original design and
move the call to strsignal out of the signal handler.  Instead, it can
set another variable; Fcall_process can check that variable and call
strsignal.

Would you like to implement this?
