I'm running the 1.1.8-2 version now and it still is happening.

Aspell was invoked from gvim, not a cygwin version. Aspell stack dumps
when called directly. I would have had more information by now if I
could figure out how to invoke gdb to run the program with command line
arguments. I ran gdb with --help and then tried "-exec=/usr/local/aspell
-c --dont-backup README". Gdb runs but does not load the program or at
least no source code is found. If I run gdb and do a File->open for
aspell the program loads and source code is opened, but then there
appears to be no way to pass command line arguments with the debugger
run command.

I did try a later version of aspell and pspell, but had the same
results. By the way the latest, 12, pspell will not build on Solaris
platforms.

I believe it to be a code problem in aspell or pspell that cropped up
due to changes in the cygwin.dll, but I need more data to prove this. I
will continue with the debugger route. I may have to hard code the
command parameters into the source code.
