Segmentation fault doing grep -P

[ljgibson]

I can consistently make grep crash on my two Gentoo machines. Would anyone be interested in trying this to see if they're getting this too?

Create a text file with a couple of lines like this:

I've got grep-2.5.1-r1 installed and it doesn't accept the -P option. No segfault.

I didn't remember to post my build information. I'm using grep 2.5.1-r7. nls and pcre use flags were set when I emerge'd grep. (I believe the pcre use flag must be set in order for grep to use perl regex's.)

I just reproduced the same crash on a RH 9 system which has version 2.5.1 of grep.

Reproduced the error and clearly it is related to the anchor as you noted.
