[cfe-commits] [Patch] Fix off-by-one error in StringLiteral::getLocationOfByte, PR10223

[Hans Wennborg]

The attached patch fixes an off-by-one error in
StringLiteral::getLocationOfByte, exposed by PR10223.

I don't really know what's going on in this code, so it would be good
if someone could review.

It seems that TokNo == getNumConcatenated() would never be true,
because it's asserted earlier that TokNo < getNumConcatenated(). I
assume the author's intention was "TokNo is the last token", i.e.
TokNo == getNumConcatenated() - 1

Thanks,
Hans
