[dominiq at lps dot ens dot fr]

------- Comment #4 from dominiq at lps dot ens dot fr  2008-09-20 07:32 -------
With the patch in comment #3, I get

FAIL: gfortran.dg/entry_1.f90  -O0  (test for excess errors)
...
FAIL: gfortran.dg/entry_1.f90  -Os  (test for excess errors)

The failure is:

/opt/gcc/_gcc_clean/gcc/testsuite/gfortran.dg/entry_1.f90:16.18:

  call indirectb (bar)
                 1
Error: Reference to ENTRY 'bar' at (1) is recursive, but procedure 'foo' is not
declared as RECURSIVE
