Commit: Fix display of 64-bit CFI and FDE frames

Agreed.

I used <c>+<c>123 since the high bits of the addresses should always be 
zero.  Any other digit (or character) indicates that something has gone 
wrong with the decoding, or creation, of the CFI and FDE frames.

I will look at tidying up the regexps as a side project for the future.

Cheers
