A very annoying situation: I'm getting a STATUS_ACCESS_VIOLATION
exception in about 2 out of 3 operations performed under cygwin/x. An
operation in this context can be starting an x application (e.g.,
xterm) or running some command from within emacs (e.g., diff or
latex).
In attempt to isolate the problem, I reinstalled cygwin from scratch
using the default settings of setup.exe + xorg-server, xinit,
xorg-docs, and X-start-menu-icons.
Next, I open a cygwin bash window and then invoke startxwin.exe .
The x-server is invoked but an xterm window does not open and the
following message appears:
***message begins***

The content of the resulting xterm.exe.stackdump file:

***content ends***
This phenomenon (or a similar one where I'm getting only 1 or two
lines of the exception and xterm does open) is very common: it happens
in about 2 out of 3 startxwin.exe invocation attempts. The same thing
happens when I'm trying to open a new xterm window from an existing
one.
I'm using Windows 7 (32 bits). This is probably a relevant info as my
old laptop (with Windows XP) works fine (once again with a fresh
installation of cygwin + cygwin/x).
I'm somewhat surprised that this problem was not reported before since
I know that my office mate suffers from it as well (she is also using
Windows 7 32 bits).
I've already tried to discuss this problem in the cygwin mailing list
(see http://cygwin.com/ml/cygwin/2010-04/msg00740.html) without a
positive resolution. Thinking about it some more, I now understand
that this problem occurs only under x, so I hope that this is the
right mailing list.
Any suggestions?
The output of cygcheck -s -v -r and the content of /var/log/XWin.0.log
are attached.
