[bug #12368] Segfault with grep -P

[Torsten Will]

Follow-up Comment #3, bug #12368 (project grep):

Yep, I had the same. I have not tried CVS version (my ssh refuses to connect
to the server, maybe ssh-key-bug?), so for the sake of completeness...
Here is a test case, I hope it helps:

$ cat xx | pgrep -P -o "(\S+) \| ((\d+\.\d+)) \| \s+(\d+\.\d+) \| ([^.
=]+)\.([^ =]+) ?= ?"?([^"]*)"?"
xmwc-stgt-de02 | 1212589022.737232 |   0.373311 | ifDescr.67 =
"GigabitEthernet3/15"
Segmentation fault


$ cat xx
--- should match ---
xmwc-stgt-de02 | 1212589022.737232 |   0.373311 | ifDescr.67 =
