afaict, stack does not exist for firefox
Keywords: testcase-wanted
Crash Signature: [@ gfxTextRun::ShrinkToLigatureBoundaries(unsigned int*, unsigned int*)] → [@ gfxTextRun::ShrinkToLigatureBoundaries(unsigned int*, unsigned int*)] [@ gfxTextRun::ShrinkToLigatureBoundaries]
From the latest crash signature [@ gfxTextRun::ShrinkToLigatureBoundaries ], the affected Firefox versions from the last 7 days are:
- Beta: 45.0b4
- Release: 43.0.4
There's only been two crash reports recent, one with Firefox 45.0.2 and one with Firefox 46.0b8. While this is clearly happening it's at such low volume that I don't think we'll be able to address it any time in the future. As such I am closing this as INCOMPLETE - please reopen if you think this is something we should address and have an idea how to fix this.
