Hi,

I recompiled abinit 5.4.4p with the Intel Compiler 10.1 and some tests 
segfault. (Compiler options are: -O3 -axSWT -fp-model precise )

ifort -V
Intel(R) Fortran Compiler for applications running on Intel(R) 64, 
Version 10.1    Build 20080602 Package ID: l_fc_p_10.1.017


gmake tests_v4 dirname=test start=04 stop=04

File abfiles.run created, starting abinit
forrtl: severe (174): SIGSEGV, segmentation fault occurred

The newest patch of the Intel 11.0 compiler now works however.
(11.0.074)

As I said I think its a problem with the Intel compiler, but annoying 
and hard to find on user side. Therefor the tip with the other compiler ;-)

Best regards,
Samuel
