The following testcase produces an error:

--------------------------------------------------------
function all_res()

implicit none

real, pointer :: gain 
integer :: all_res

allocate (gain,STAT=all_res)

end
--------------------------------------------------------


--------------------------------------------------------
gfortran -c test_gfortran3.f90 
test_gfortran3.f90:8.27:

allocate (gain,STAT=all_res)
                          1
Error: STAT expression at (1) must be a variable
--------------------------------------------------------

Tried with gfortran 4.2.1 and r127057. NAG and Lahey compiler work with this
code. Platform i686, Debian lenny.

------- Comment #1 from burnus at gcc dot gnu dot org  2007-07-30 15:45 -------
The problem is that "all_res" is not only the name of a (result) variable but
also of the function itself.

The following - not regtested - should work (also if one uses ENTRY rather than
FUNCTION).

------- Comment #5 from burnus at gcc dot gnu dot org  2007-08-01 18:00 -------
FIXED in GCC 4.3; as it is not regression [and no wrong-code bug either] I will
not backport it to 4.2.x or 4.1.x -> mark as fixed.

Note: GCC gfortran 4.3.0 nightly builds are e.g. available at
http://gcc.gnu.org/wiki/GFortranBinaries
