Compile:

Error: Symbol 'a1' at (1) has no IMPLICIT type
foo.f:4.72:

Error: Symbol 'a2' at (1) has no IMPLICIT type

nonsensical error when there shouldn't be one?

Confirmed on x86_64-apple-darwin10.3.0 for 4.5.0 and trunk, but not 4.4.4,
hence it is a regression.

------- Comment #4 from burnus at gcc dot gnu dot org 2010-09-22 20:22 -------
As you might have guessed, the error is with regards to the arguments of MAX
which are A1 and A2.
The arguments are defined as BT_UNKNOWN, cf. in intrinsics.c:
add_sym_1m ("max", GFC_ISYM_MAX, CLASS_ELEMENTAL, ACTUAL_NO,
BT_UNKNOWN, 0, GFC_STD_F77,
gfc_check_min_max, gfc_simplify_max, gfc_resolve_max,
a1, BT_UNKNOWN, dr, REQUIRED, a2, BT_UNKNOWN, dr, REQUIRED);
The backtrace shows:
#0 gfc_set_default_type (sym=0x144e6b0, error_flag=1, ns=<value optimized
out>)
at fortran/symbol.c:263
#1 0x00000000005328d7 in resolve_formal_arglist (proc=0x144d1f0)
at fortran/resolve.c:303
