I refreshed my Cygwin installation over the weekend, and ever since I have
not been able to run gdb under emacs as I previously had done. I use M-x
gdb to start the gud interface, and as soon as I enter the "run" command, I
get a message saying either "Debugger aborted (core dumped)" or a similar
message reporting a segmentation violation in the debugger. I have tried
various combinations of previous versions of emacs and gdb, but all have
the same result. gdb run from a regular shell window works fine. I assume,
then, that it's something else in my environment that changed with the
refresh last weekend. I don't recall when my most recent previous refresh
of the Cygwin installation was, but it's probably on the order of a couple
or three months, so whatever the problem is, it might not be
terribly recent.

Thanks for any suggestions.
