segfault in xwin-xdg-menu.exe

segfault in xwin-xdg-menu.exe

[Fabio Rossi]

I have just made a fresh cygwin installation on windows 10 pro 32bit using setup 2.891. I have selected xorg-server, xinit, vim and gdb packages. I have modified the Xwin server configuration as described in https://x.cygwin.com/docs/faq/cygwin-x-faq.html#q-startxwinrc-exit and later I have successfully started it by using the action "cygwin-x\xwin server" under Windows programs menu. The X server is running with display :0.0 and its icon is visible in the tray bar.

On another system installed months ago I have the xdg menu application already running (it's automatically started by the xwin startup script) but I didn't need to follow the above mentioned trick described in the FAQ.

In a cygwin terminal I then try starting manually xwin-xdg-menu by using:

$ DISPLAY=:0 xwin-xdg-menu.exe

but I get a segmentation fault. With gdb I get the following backtrace:

$ DISPLAY=:0 gdb xwin-xdg-menu.exe

I do not see any obvious issue, sorry.
May be xwin-xdg-menu needs need a font you don't have

Try with strace to see what is trying to do/open before the segfault

DISPLAY=:0 strace -o /tmp/xwin-xdg-menu.strace /usr/bin/xwin-xdg-menu.exe

Yeah, this is the same problem, which is under investigation.

See also https://cygwin.com/ml/cygwin/2018-05/msg00152.html for another

I have recompiled fontconfig and solved the issue as suggested in the other topic. Is it possible to update the binary packages installed by setup.exe?
