Does the "catch syscall" approach work when the exit is due to a signal? I would have thought not, but I did not test it. "catch exit" works via PTRACE_O_TRACEEXIT. We go back and forth about the utility of it, FWIW. I wrote most of what I did just to learn more about infrun and the remote protocol; then one day we found some actual use for it :-) Tom
