Subject: libharfbuzz0 1.7.6-1 update causing xwin-xdg-menu.exe to crash
Date: Thu, 19 Apr 2018 21:15:00 -0000 [thread overview]
Message-ID: <30aa068b-574f-8770-d8f3-eb037c038709@scrc.umanitoba.ca> (raw)
Has anybody else run into this problem? I've done two installations of
Cygwin/X on Windows 10 systems this week, and they both had problems
with the XWin Server dying just a few seconds after starting up. I
traced the problem back to xwin-xdg-menu.exe getting a Segmentation
fault, which then causes XWin Server to exit. I hacked an alternate
.startxwinrc file to prevent XWin Server from dying (it ends with a
"sleep infinity"), so I could debug it further.
With the XWin Server running reliably, I then ran "strace
xwin-xdg-menu.exe" and saw that it got a segmentation fault just after
reading a TTF font from the Windows Font directory (bahnschrift.ttf if
it matters). I noticed there were two recent library updates related to
font handling, so I tried back out to the previous version for each. It
turns out that when I reverted to version 1.7.4-1 of libharfbuzz0,
xwin-xdg-menu.exe stopped crashing.
If it matters, both these systems are the Fall Creator's Update (1709)
of Windows 10 64-bit, and I'm running the 32-bit version of Cygwin.
Hopefully someone can track down and fix this recent bug!
Thanks,
Gilles
