For at least one application, the crash is in:

    0   libvDSP.dylib                 	? + 117458
    1   com.apple.CoreText            	TRun::TRun(TRun const&, CFRange, TRun::SubrangingStyle) + 850
    2   com.apple.CoreText            	CTGlyphRun::CloneRange(CTRun const*, CFRange, TRun::SubrangingStyle) + 142
    3   com.apple.CoreText            	TLine::SetLevelRange(CFRange, unsigned char, bool) + 162
    4   com.apple.CoreText            	TLine::SetTrailingWhitespaceLevel(unsigned char) + 70
    5   com.apple.CoreText            	TRunReorder::ReorderRuns(TBidiLevelsProvider const&, TLine&) + 122
    6   com.apple.CoreText            	TTypesetter::FinishLineFill(TLine&, double, double) const + 142
    7   com.apple.CoreText            	CTTypesetterCreateLine + 131

I'm not familar enough with CoreText internals to guess what's going wrong, though. :)
