segmentation fault on exit in Insight 5.0

[Nicholas_Karagas at cirilium dot com]

Hello again,

I tried downloading the gdb/Insight 5.0 release, and still have the same
problem (SIGSEGV when exiting).  Here's the complete backtrace (actually,
all output) from debugging the Insight session.  All I did was start
Insight with my .gdbinit file and immediately exit.  Note that the line
numbers for remote.c may not match yours exactly, as I have some stuff
specific to our particular setup in there.  I am connecting to a remote
m68k via Remote/Serial at 38400 baud.  I am running Cygwin 1.1.0(0.18/3/2)
(from uname -r) on WINNT 4.0 (Build 1381: Service Pack 6).  Any help on
this would be greatly appreciated.  Thanks.
