For those that enjoy fixing bugs:

% echo foo | sed
's/..a|..b|..c|..d|..e|..f|..g|..h|..i|..j|..k|..l|..m|..n|..o|..p//g'

Will crash both native and p9p sed.

Yes, I know it is a nonsensical expression, but it is the simplest one
that still made it crash, I have lost the original version which was
much more complex.

Note that providing two characters as input will still crash, but if
the input line is a single character it wont crash.

I have been meaning to get all the fun of tracking this one down
myself for a while, but seems that I never get to it, so I will let
others enjoy the fun of fixing it.

Peace
