Hi,
By installing firefox-dbg package, I was able to obtain the attached
backtrace for the bus error problem. According to it, the crash happens on
line 5105 of layout/generic/nsTextFrame.cpp, which looks like this:
5102 while (aNumChars-- > 0) {
5103 // XXX: If you crash here then you may see the issue described
5104 // in http://bugzilla.mozilla.org/show_bug.cgi?id=36146#c44
5105 *cp2-- = PRUnichar(*cp1--);
5106 }
Judging by the comments in the mentioned upstream bug, bus error is caused
by an unaligned access somewhere in this line.
Best regards,
