Error: Can't convert TYPE(c_ptr) to INTEGER(4)

[Andrew Benson]

After checking out the latest gfortran 4.6 updates (revision 163780) this 
morning I'm getting an error that seems to be related to "c_null_ptr". I've 
attached a minimal test case that shows this error.

$ gfortran -c test.F90 -o test.o
test.F90:5.30:

     type(c_ptr) :: accelPtr = c_null_ptr
                              1
Error: Can't convert TYPE(c_ptr) to INTEGER(4) at (1)

The test case compiles OK under gfortran 4.4. The problem must have arisen 
between revisions 163661 and 163780 (my code compiled and ran successfully 
under 163661). Note that the presence of the "allocate" statement in the test 
case is required to cause the error - commenting it out results in a 
successful compile.

I'll try to locate the responsible revision unless anyone can figure out what 
the problem is first!

-Andrew.
