Re: [RFA] fix crasher on detach command

Hi,

The circumstances are, detach from a remote target that doesn't have
threads.  Remote.c leaves the PID arbitrarily as "42000", and
target_detach calls remove_breakpoints_pid, which crashes because
find_inferior_pid returns NULL.

It shouldn't matter that the PID is arbitrary; there should be an inferior with that PID in the inferior list. This probably means that the inferior got its PID cleared to 0 already when you get here? How?

It was a bad connect, which aborted part way through. So yes, we're in an inconsistent internal state.


What's the backtrace like at the time of the crash?  I assume
the remove_breakpoints_pid call is coming from within target_detach?

It's fairly normal, target_detach is called by detach_command.
