Hi,

Got a seg fault using latest CVS version of grep. Tracked it down and
here's a diff of grep.c:

545c545
<         while ((match_offset = (*execute) (ibeg, ilim - ibeg,
&match_size, 1))
---
 >         while ((match_offset = (*execute) (ibeg, lim - beg,
&match_size, 1))

It was failing because ibeg was being increased in the while loop when a
match was found, thus reporting the wrong size to GExecute.

Thanks,

Ed
