I encountered the same bug in gfortran 4.7.0 20110329 and 4.5.2.
Are there any updates on this bug?

I did not encounted this bug with g++ 4.7.0 20111126, but do encounter it from
g++ 4.7.0 20111203 through g++ 4.7.0 20120128. Hopefully that helps narrow
things down.

A simple workaround for this bug seems to be:
cptr = c_loc(obj1%array(1,1))
in the above example. It compiles and appears to be doing what it should.
Maybe that also helps narrowing it down.

------- Comment #2 from burnus at gcc dot gnu dot org 2009-08-04 16:14 -------
The issue is that the expression is an array ("expr->rank > 0") but the symbol
itself is not, only it's component.
==16545== Invalid read of size 4
==16545== at 0x55343F: gfc_conv_procedure_call (trans-expr.c:2441)
==16545== by 0x547595F: ???
==16545== by 0x4FBD06: gfc_match_actual_arglist (primary.c:1670)
That's the last line in:
if (sym->intmod_sym_id == ISOCBINDING_LOC)
[...]
if (arg->expr->rank == 0)
gfc_conv_expr_reference (se, arg->expr);
else
{[...]
/* We should want it to do g77 calling convention. */
f = (fsym != NULL)
&& !(fsym->attr.pointer || fsym->attr.allocatable)
&& fsym->as->type != AS_ASSUMED_SHAPE;

Created an attachment (id=18299)
--> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=18299&action=view)
Source file to cause the segfault
I used option -save-temps, but could not find a *.i file, so I have attached
the *.f90 file instead.
