grsecurity forums

Hi,

I've several problems with the current release grsecurity with 2.6.14.2 (PAX is completely disabled, only loggin options enabled). I cannot build glibc-2.3.5 and gcc-4.0.2. If I build other tools, I sometimes get similar logs, too:

If I disable grsecurity completely, I've no problems.

Can anyone help me?

Best regards, Sven

what may help is if you enabled coredumping and gathered some info from the coredumps (details on this were posted here and/or the mailing list in the past).
