Hopefully someone who reads this might be interested in fixing bugs rather than
ignoring the problem, the following could be useful:

   export WINEDEBUG=+font,+xrender,+xrandr,+synchronous

In the trace you get:

   trace:xrender:UploadGlyph buflen = 127920. Got metrics: 78715x13 adv=13175,0
origin=-1,11
   err:seh:setup_exception_record stack overflow 940 bytes in thread 0009 eip
7bc39bcf esp 00240f84 stack 0x240000-0x241000-0x340000

Note that the font metric is clearly WRONG (no possible font could be 78000
pixels wide) and the buflen is much larger than expected (typical buflen values
in UploadGlyph are less than 100 bytes). This shows errors in the font metric
calculation.

Anyone having similar problems should trace with similar WINEDEBUG and search
for the UploadGlyph line with the broken metric values. If you have similar
problems please post to this bug, maybe get it opened again.

As a bit of additional info, I see lines like this in the trace:

   trace:font:WineEngGetGlyphOutline 4,8,(0,8),5,0

Almost always these are small numbers, but right before the bug hits I see
larger numbers like so:

   trace:xrender:get_xrender_format Returning wxr_format=0
   trace:font:GetGlyphOutlineW (0x1d0, 0056, 0081, 0x33e338, 127920, 0x1fea40,
0x73632ab6)
   trace:font:WineEngGetGlyphOutline 0x1a0dc0, 0056, 00000081, 0x33e338,
0001f3b0, 0x1fea40, 0x73632ab6
   trace:font:WineEngGetGlyphOutline font transform 1.000000 0.000000 0.000000
1.000000
   trace:font:WineEngGetGlyphOutline Vec 0,704
   trace:font:WineEngGetGlyphOutline Vec 0,-128
   trace:font:WineEngGetGlyphOutline Vec 384,704
   trace:font:WineEngGetGlyphOutline Vec 384,-128
   trace:font:WineEngGetGlyphOutline transformed box: (-64,704 - 5037696,-128)
   trace:font:WineEngGetGlyphOutline 78715,13,(-1,11),13175,0


This is the only place I see the "Vec" lines and also the only place I see
large numbers in the WineEngGetGlyphOutline result so that might be something
to look for.
