I've noticed the same problem. I can get it to work with opensuse (version ?)
with a recent gcc version, but not fedora 12... so it might be a fedora
issue vs a gcc issue, but I can't be absolutely sure about it.

Here are some notes that I sent to myself in the past regarding this issue:

===================================================================================
opensuse (version?) x86_64; Xeon X5355; gcc/gfortran 4.1.2 MSI Calhoun Cluster

Fails to compile rism/_safemem.f
gfortran -c -O3 -ffree-form -o safemem.o _safemem.f
_safemem.f: In function ‘reallocate_pointer_1d_character’:
_safemem.f:914: internal compiler error: Segmentation fault
Line 914 reads:
    IF(ASSOCIATED(p)) then


===================================================================================
opensuse (version?) x86_64; Xeon X5355; gcc/gfortran 4.3.3 MSI Calhoun Cluster
opensuse (version?) x86_64; Xeon X5355; gcc/gfortran 4.4.0 MSI Calhoun Cluster

Compiles and PASSES all NAB tests


===================================================================================
Fedora 12 x86_64; Nehalem E5520; gcc/gfortran 4.4.2 Machine 1
Fedora 12 x86_64; Nehalem E5520; gcc/gfortran 4.4.3 Machine 1
Fedora 12 x86_64; Nehalem E5520; gcc/gfortran 4.4.3 Machine 2
Fedora 12 x86_64; Nehalem E5520; gcc/gfortran 4.4.3 Machine 2 with -m64 flag My machine

All nab tests fail with garbled strings.
Machine 1 and machine 2 are identical. Tested on both to make sure
that I hadn't done something weird to (my) machine 1.
