Subject: [gentoo-security] Gcc version on affected kernels. Was: The brk() overflow

I have a machine running 2.4.21_pfeifer-r1_pre3 with grsec activated
(big kernel, no modules support) and the "exploit" build ok with both
nasm  0.98.38 and 0.98.34, but with both versions when i tried to run
humpback@www humpback $ ./a.out 
Segmentation fault

and in messages:
PAX: From task a.out:11228, uid/euid: 5005/5005, may have
attempted to execute invalid code at 00001ead

This machine is a old gentoo 1.1 release (gcc version 2.95.3 20010315
(release)). Any ideas if it is related?
