I've been unable to debug the following failure because it results in the
entire cygwin X server crashing. The code involved is from building the
Prima::OpenGL module which fails running test t/02_basic.t in the call to
glXMakeCurrent() in the x11.c file.
I've attached an edited version of the cygcheck output, the XWin.0.log, and the output
error message from the mintty console which appears to have the "final gasp"
message which does not make it into XWin.0.log (presumably because of the crash):
winGetWindowInfo: forcing window to exist
assertion "pWin->parent" failed: file
"/wip/cygport-git/xorg-server/xorg-server-1.15.0-3/src/xserver-cygwin-1.15.0-3/hw/xwin/winmultiwindowwindow.c",
line 63, function: isToplevelWindow
Thanks for the bug report and reproduction steps.
I think this looks like a bug I fixed in 1.15.1-1, where the X server
would crash if OpenGL was used on the (hidden) root window in
multiwindow mode. [1]
In any case, can you please retry with the latest X server version.
