This one is mine, it's apparently due to my recent wide-characters patch. It
can be reproduced on x86_64-linux by compiling the following preprocessed file
under valgrind:
# 1 "../../../trunk/libgfortran/generated/_abs_c4.F90"
# 1 "C:\\msys\\1.0.10\\home\\FX\\ibin\\i586-pc-mingw32\\libgfortran//"
# 1 "<built-in>"
# 1 "<command-line>"
# 1 "../../../trunk/libgfortran/generated/_abs_c4.F90"

# 1 "./c99_protos.inc" 1
# 39 "../../../trunk/libgfortran/generated/_abs_c4.F90" 2
elemental function _gfortran_specific__abs_c4 (parm)
complex (kind=4), intent (in) :: parm
real (kind=4) :: _gfortran_specific__abs_c4
_gfortran_specific__abs_c4 = abs (parm)
end function

(it evens then manages to crash valgrind with "VALGRIND INTERNAL ERROR" and
then "valgrind: the 'impossible' happened"). Thanks Aaron for reporting it,
I'll fix it as fast as I can.
