Details:

Hi,

i have old rh7 machine with updates from redhat.

I had to compile new version of grep.

Compilation went good - 2.5, 2.5.1 and 2.5.1a.

configure script was called with:
--prefix=/usr 
--disable-largefile 
--disable-nls


But after:
address@hidden grep-2.5]# ./src/grep
Segmentation fault (core dumped)

 strace ./src/grep
