I have invastigated a bit more the problem. I'm still using GCC4.4.3 on
a fedora core 12 workstation. I have reinstalled GCC4 and the standard
C/C++/fortran libraries. The AmberTools 1.3 have been compiled as following:

    configure_at -nosleap gcc
    make -f Makefile_at

Then I went to the test directory and modify Makefile_at file to skip
the nab test. The test failed at:
load and saveamberparm: 94 ff
When I check the log, the failure happens when loading the nucleic acids:

>> parm94 = loadamberparams parm94.dat
    Loading parameters: /home/software/amber11/dat/leap/parm/parm94.dat
    Reading title:
    PARM94 for DNA, RNA and proteins with TIP3P Water. USE SCEE=1.2 in
    energy progs
    (UNKNOWN ATOM TYPE: IM)
    (UNKNOWN ATOM TYPE: Li)
    (UNKNOWN ATOM TYPE: IP)
    (UNKNOWN ATOM TYPE: K)
    (UNKNOWN ATOM TYPE: Rb)
    (UNKNOWN ATOM TYPE: Cs)
    (UNKNOWN ATOM TYPE: IB)
    (UNKNOWN ATOM TYPE: EP)
>> #
>> # Load DNA/RNA libraries
>> #
>> loadOff all_nucleic94.lib
    Loading library: /home/software/amber11/dat/leap/lib/all_nucleic94.lib
    Loading: DA

At that point, I don't see what to do. My feeling is that the problem is
related to a weird configuration of GCC4.4.3 and or the C/C++ libraries.
I don't know if it's specific to fedora core 12, GCC4.4.3 or if I did
something really wrong during the install. I think I will reinstall
again my machine, but with another linux this time. Maybe CentOS?

Regards,
Nicolas
