      I posted this query a while ago, i still have no answers, I am
currently working on Bug 27687 (PrintStackTraces), so the reason for the
failure is the erroneous unwinding of the frames from the zeroth frame. The
error is not detected in AddOneMoreFrame, since it only checks for 2 more
frames, if it was checking more frames in AddOneMoreFrame, it would have
detected the error. Now my questions are ->

->  is that is there any specific reason for only checking 2 frames instead
of more ?
->  Why no make the EH CFI based unwinder the default one and make the
assembly the fallback ?

Best Regards,
A Ravi Theja
