[OOPS] less /proc/net/igmp

[Marcel Sebek <sebek64@post.cz>]

This Oops appears on 2.5.74+ kernels (including 2.6.0-test4) when
I'm trying to read /proc/net/igmp with 'less', 'cat' displays
the file content without oops:

LILO boot: linux init=/bin/bash

EIP points to the begin of the function clr_linenum() in
less-374/linenum.c:78 (instruction 'push %ebp').

Kernel is compiled by gcc-2.95.4 (20011002) from Debian woody.
Less is from woody and also from the original sources.
