Re: segmentation faults

Hi Jeroen,

/lib/i686 is just where my optimized libpthread.so.0
was located.  This is the thread I got the fix from
http://thread.gmane.org/gmane.linux.cluster.openmosix.general/9244

The gist of it is if you have more than on
libpthread.so.0 on your system and they are different
it can lead to problems.
