Crash in file search

[akorop]

mc crash in file search for content if "Whole words" is marked. Failure occurs after at least one file is found. System - ubuntu 10.04, WM - openbox.
At me, this bug present in few latest versions, including 4.8.1. This bug NOT present in the 4.7.0 from Ubuntu repository.

ubuntu 10.04

Such bug was never occurred for me. I'm unable to reproduce it. Please ask your mc maintainer to play with various versions of glib2 and pcre.
