I have a simple C program I place in my win32 system dir to "catch"
any references to "gvim" in the system dir and have it really started
from the actual program dir. This is only for the win32-version of gvim --
the cygwin version I call in the shell, I call using "vi". The "vim" version
looks in the cygwin dirs for it's supporting files.
It had been working "fine" and recently has broken in some difficult to debug
cases (like when launched from explorer on a text file). At the same time
some of my 'bash.exe' invocations from the windows SHELL (explorer) have
started failing -- the message flickers by too fast for me to see them.
I manage to duplicate the gvim error in a 'cmd.exe' shell though and thought
I'd throw it out and see if it looked familiar to anyone. I tried running
rebaseall, to see if that changed anything. Not. Nada on recompile/new
binary. It appears, if I execute the same "gvim.exe" file in a different
directory, it works. If I execute a cygwin shell first, then I can
execute the binary in the system32 directory and I get no error (it just
works).
Am sending this out now to see if the error messages look familiar to
anyone. The error messages (except the last one) aren't coming out of
my program. The program is included, below the error. It seems
"trivial" enough... Not sure why it would die when called from
windows progs, but not cygwin progs...
If I can't trace it down to something odd in my config, I'll submit
a cygcheck...but off hand, not sure of all the differences between the
working and non-working cases and the error is just strange...
(I have plenty of memory, disk, resources, whatever...not at issue
since I can run 'ash', then the 'gvim' file (same one) and it works).
Here's the messages:
