[Bug fortran/42783] [4.5 Regression] Bogus Array bounds violation with optional array argument

[pault at gcc dot gnu dot org]

------- Comment #2 from pault at gcc dot gnu dot org  2010-01-18 17:31 -------
Confirmed.

A weird and wonderful feature of this bug is that it disappears for -O2 and
higher :-)

The problem comes about because fsym->backend_decl is being used, which is
incorrect if the argument is missing because this does not correspond to the
declaration for the string.  Instead, the function gfc_conv_expr_present should
be used.

A patch is regtesting right now.

Paul
