Just to try to get the obvious out of the way first... are you sure it's
not GDBserver itself crashing?  GDBserver is a C++ program, so it's
possible that an exception is thrown and not caught in it.

Can you paste the logs of a session that shows your problem?

GDBserver and your program are running on Windows IIUC?
