For over a month now I've been having issues with my xterms in Cygwin.
If I try to access *any* menu item under the Ctrl-<mouse button> menu
items (change font, turn on/off scrollbar, redraw window, etc.), my
xterm crashes the moment I un-press my mouse button. I don't access
them all that often, so I don't know how long the issue has been
around, but it's been a couple of months now.
I've tried launching it with an empty .Xdefaults file (home dir) and
by moving my .bashrc/.bash_profile files out of the way - still the
same result. I've also gone out and downloaded the latest XTerm code
and have a version compiled with debugging, but my C skills are really
rusty and I'm not seeing anything terribly useful in gdb (I set my
CYGWIN env var to "error_start=dumper -d %1 %2" so I would get core
dumps). I compiled a version with a different "DEFCLASS" set so that
I *know* it's not a bad resource or resource file.
I'm running 64 bit on Windows 7. More details in the attached cygcheck.out.
Anybody else on 64bit Cygwin / Win 7 having the same issues?
Thanks for reporting this issue. I can reproduce it.
This appears to be an issue with Xt, as a Cygwin-specific patch does not
work correctly on x86_64 when another DLL which is using Xt is loaded
>2GB away from it.
Until we have a fix, you *might* be able to work around this by rebasing
the DLLs, e.g. in the specific case of xterm, which uses Xaw:
cd /usr/bin
rebase -v -b 0x400000000 cygXt-6.dll
rebase -v -b 0x410000000 cygXaw-7.dll
