There are no crash reports matching libsystem_c.dylib@0x27ce2 anymore.
Still, it might have just moved to one of the other gazillion
libsystem_c.dylib@NNNN we have so that doesn't say much.
What we really want to know is if gfxUserFontSet::OnLoadComplete
or ots::OTSStream::Pad occurs in any crash stack *at any depth*.

Looks like the stack is in font handling code.
