[PD] *** glibc detected *** debian/unstable

[Gerda Strobl]

Hi Thomas,

today I got new pool-the double-free problem doesn't happend 
anymore-still pd is crashing.
I am using gcc version 3.3.6 --
In the  flext config-lnx-pd-gcc. txt Georg told me to try pentium-m 
because I dont have a pentium4 -but this doesn't change.
