Firefox Crash [@ _cairo
_scaled _glyph _page _can _remove ]
Seen while reviewing trunk crash stats. Mostly all trunk crashes, but one from 3.6.x: http://crash-stats.mozilla.com/report/list?signature=_cairo_scaled_glyph_page_can_remove. First crash showed up in crash stats using 2011041300. https://crash-stats.mozilla.com/report/index/30602aeb-cb56-4af9-9f1a-66bf42110602 Frame Module Signature [Expand] Source 0 xul.dll _cairo_scaled_glyph_page_can_remove gfx/cairo/cairo/src/cairo-scaled-font.c:2672 1 xul.dll cairo_hash_table_random_entry gfx/cairo/cairo/src/cairo-hash.c:393 2 xul.dll _cairo_hash_table_resize gfx/cairo/cairo/src/cairo-hash.c:262 3 xul.dll _cairo_cache_remove_random gfx/cairo/cairo/src/cairo-cache.c:219 4 xul.dll _cairo_cache_shrink_to_accommodate 5 xul.dll moz_cairo_scaled_font_glyph_extents gfx/cairo/cairo/src/cairo-scaled-font.c:1569 6 xul.dll gfxFont::SetupGlyphExtents gfx/thebes/gfxFont.cpp:1565 7 kernel32.dll RtlFillMemoryStub 8 xul.dll gfxTextRun::FetchGlyphExtents gfx/thebes/gfxFont.cpp:4274 9 mozalloc.dll moz_xmalloc memory/mozalloc/mozalloc.cpp:100 10 xul.dll gfxFontGroup::MakeTextRun gfx/thebes/gfxFont.cpp:2414 11 xul.dll TextRunWordCache::MakeTextRun gfx/thebes/gfxTextRunWordCache.cpp:732
The two crashes on 3.6.17 were using Linux. All other crashes are using trunk.
OS: Mac OS X → Windows 7
It looks like this was only happening on 64bit. The attached patch may fix the problem.
Good catch. Can we rely on uintptr_t being defined though as we cannot rely on stdint.h being available?

I was trying to see if this is fixed for Fx7 since the flag "status-firefox7" is set to "fixed", but I couldn't. Is there a test case or any steps / guidelines for this bug that can be used to verify the fix? Thanks
qa+ for QA verification in Firefox 7. Please check crashstats for occurrences of this crash in Beta 5 or 6.

There is one crash with the signature _cairo_scaled_glyph_page_can_remove for the build FX 7 build: https://crash-stats.mozilla.com/report/index/3d785371-0b59-4b9a-843e-8a67c2110917 It's not clear if this is related to the issue reported or not.
That crash must have been from an earlier build. I don't see any crashes for this stack in trunk, or Beta 5 or Beta 6 in the last week.

Marking this verified fixed based on recent crash data. This is only reported twice in the last week and only on 6.0.2.
