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.
