Dear Axel,

the reason why I orignally did not try your suggestion (which, I think, you 
have posted before) was I wanted to make the most or the i7 chip I have (or 
the E5520 on the actual computational node).

I actully tried is just 4 mins. ago:

ifort -c -D__INTEL -D__FFTSG -D__FFTW3 -D__LIBINT -I/opt/intel/fce/11.1/046/include/ -I/opt/fftw3/3.2.1/include -O2 -unroll -march=pentium3 -mtune=core2 -pc64 -fpp -heap-arrays 
64 -free -D__COMPILE_ARCH="\"Linux-x86-64-intel\"" -D__COMPILE_DATE="\"Tue 
Aug  4 20:19:45 BST 
2009\"" -D__COMPILE_HOST="\"linuxtut02\"" -D__COMPILE_LASTCVS="\"D\"" /home/sassy/build/cp2k/rt/cp2k/makefiles/../src/semi_empirical_parameters.F
: catastrophic error: **Internal compiler error: segmentation violation signal 
raised** Please report this error along with the circumstances in which it 
occurred in a Software Problem Report.  Note: File and line given may not be 
explicit cause of this error.

compilation aborted 
for /home/sassy/build/cp2k/rt/cp2k/makefiles/../src/semi_empirical_int_utils.F 
(code 3)
make[1]: *** [semi_empirical_int_utils.o] Error 3
make[1]: *** Waiting for unfinished jobs....

I had to add the -free in order to make it work. So, once I reach an ICE I 
don't board it (unless it is in Germany :D ) but report the bug to Intel. 
Which I actually would love to do but the last time I tried it their website 
did not work properly.

The OS is Debian Lenny with gcc-4.3.2 installed. It was actually the seriell 
build and not the parallel build.

Right now I am not too concerned about it, I put that down as one of the Intel 
compiler problems. So I don't really want to wast too much time on that to be 
honest.

All the best from Glasgow!

Jörg
