Without option and when compiled with the 20070316 snapshot on OSX 10.3.9
gcc/testsuite/gfortran.dg/pointer_intent_1.f90 yields an executable
which segfault, see:

http://gcc.gnu.org/ml/fortran/2007-03/msg00345.html

but ignore the crash log I have posted. The right one is:

------- Comment #1 from dominiq at lps dot ens dot fr  2007-03-24 22:28 -------
xlf yields a bus error without optimization and -O, and abort with -O3.
g95 gives the following errors:

In file pointer_intent_1.f90:39

      nullify(t%point)
                1
Error: Cannot NULLIFY the INTENT(IN) pointer 't' at (1)
In file pointer_intent_1.f90:42

      deallocate(t%point)
                 1
Error: Cannot DEALLOCATE INTENT(IN) dummy variable 't' at (1)

------- Comment #2 from burnus at gcc dot gnu dot org  2007-04-10 19:26 -------
Accept. I somehow missed the email/PR while reading all the messages after a
conference.

Patch at:
http://gcc.gnu.org/ml/fortran/2007-04/msg00105.html


(In reply to comment #1)
> xlf yields a bus error without optimization and -O, and abort with -O3.
This is ok as the variable is not allocated.

> g95 gives the following errors:

I believe this is wrong. The pointer "t" is not modified at all, only the
component "point" of the pointer target is.
That is: Modifying t%x and t%point is ok, but changing the assignment of the
pointer "t" itself is not allowed.
