Seemingly, we overlooked some issue when checking the debug patches. Compiling
octopus (tddft.org) with gfortran now gives an ICE:
$ gfortran -g tmp1.f90 tmp.f90
tmp.f90:2: internal compiler error: Segmentation fault
Valgrind shows (when compiling tmp.f90, tmp1.f90 is OK):
==8754== Invalid read of size 1
==8754== at 0xB5B660: htab_hash_string (hashtab.c:812)
==8754== by 0x54B12E: lookup_filename (dwarf2out.c:15573)

Test files (note: There is no ICE if one puts the two files into a single
file).
---------- tmp1.f90 -------------
module c_pointer_m
use iso_c_binding, only : c_ptr, c_associated, c_null_ptr
implicit none
contains
subroutine set_null(ptr)
type(c_ptr), intent(out) :: ptr
ptr = c_null_ptr
end subroutine set_null
end module c_pointer_m
------------ tmp.f90 ---------------
module string_m
use c_pointer_m
implicit none
end module string_m

Confirmed. s.file is NULL:
#2 0x0820ff95 in add_src_coords_attributes (die=0xb7c2e428, decl=0xb7cb00d0)
at /home/richard/src/trunk/gcc/dwarf2out.c:12442
12442 add_AT_file (die, DW_AT_decl_file, lookup_filename (s.file));
(gdb) print s.file
$1 = 0x0

Created an attachment (id=16172)
--> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=16172&action=view)
gcc44-pr37287.patch
Patch I'm going to bootstrap/regtest.
For DW_TAG_module with DW_AT_declaration we really shouldn't add
DW_AT_decl_file and DW_AT_decl_line attributes, we don't know in which file
they are defined (and even if we read it from *.mod, it is a different file
than the CU ever includes).
