works with gfortran-4.3 but segfaults with gfortran-4.4

[Kamaraju S Kusumanchi]

I am not sure if it is a Debian bug or gfortran's bug. Consider the
following code attached (5 files)

If I use the gfortran-4.3 the code compiles and executes fine
$gfortran-4.3 -g la_erinfo.f90 la_auxmod.f90 f77_lapack_double.f90
f95_lapack_double.f90 la_dgesvd.f90 la_dgesdd.f90
dummy.f90 /usr/lib/liblapack.so.3gf

$./a.out
 calling la_gesvd
 calling la_gesdd

But If I use the gfortran-4.4 compiler, the code gives a segmentation fault

$gfortran-4.4 -g la_erinfo.f90 la_auxmod.f90 f77_lapack_double.f90
f95_lapack_double.f90 la_dgesvd.f90 la_dgesdd.f90
dummy.f90 /usr/lib/liblapack.so.3gf

$./a.out
 calling la_gesvd
 calling la_gesdd
Segmentation fault (core dumped)

Can someone please tell me if I am doing anything wrong or if this is a bug
in gfortran-4.4?

thanks
