IBM power6: internal ERROR PHASER: 16 -31 2 -31

Hello,

I'm trying to get vasp 4.6.31 compiled(with the xlf compiler) on a power6 machine. When I just recompiled vasp(not vasplib) everything went fine, but when I also compile the vasp.lib on this machine vasp sometimes crashes giving the above error...
adding the flag -qpdf1 in the makefile of vasp(not lib) makes the error go away...but I'm affraid it might still be there and cause mayhem when I can't check.

I have some small benchmark-jobs and these run perfectly...always.
Anyone who knows what this problem is and how it can be solved?

thx
Danny

strange, please make sure that you use the same compiler... for vasp.4.6 and vasp.4.lib and compile nonlr.F with lowest optimization

switched the optimization for the vasp4.lib to -O3 and the problem seems to have disappear...
