[gentoo-hardened] execution attempt in: <anonymous mapping> when emerging glibc-2.3.3_pre20040420

[Jerome Poggi]

Hi,

I get a big strange think :

I emerge the last glibc (sys-libs/glibc-2.3.3_pre20040420) and I get
think buggy thinks :
My X windows manager was killed, so I try to know why and I had this in
my syslog log file :

I use a 2.6.4-hardened-r3 kernel with Pax and Grsec activated.
Linux efflam 2.6.4-hardened-r3 #5 Fri Apr 2 15:32:48 CEST 2004 i686 Pentium III (Coppermine) GenuineIntel GNU/Linux

Did somebody get a think like this ?

Now I will try to recompile glibc in a tty and not in X

I backup the temp dir for history, and in case of :)
