On FreeBSD I get
REMOVE:kargl[6] gfc4x -o z a.f90
a.f90:2.12:

  print *, 2**huge(0) 
            1

REMOVE:kargl[7] gfc43 -o z a.f90
a.f90:2.12:

REMOVE:kargl[8] gfc4x --version

REMOVE:kargl[11] pkg_info | grep gmp
libgmp-4.2.4        A free library for arbitrary precision arithmetic
REMOVE:kargl[12] pkg_info | grep mpfr
mpfr-2.4.1          A library for multiple-precision floating-point computation

Do your gmp/mpfr libraries pass their testsuites?  Do you have more
than one version of one of these libraries installed.

The error message indicates that gmp is broken or perhaps NetBSD's
malloc implementation.
