libharfbuzz0 1.7.6-1 update causing xwin-xdg-menu.exe to crash




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
