> Let me have a look.
The attached patch works with your test, I just moved the checks into
the loops.
I'm now checking the patch against the full fortran testsuite.
I'm (finally) fine with that version, what do you think of it?

Subject: [PATCH] Fortran: error recovery for invalid types in array
constructors [PR107000]
gcc/fortran/ChangeLog:
PR fortran/107000
* arith.cc (gfc_arith_error): Define error message for
ARITH_INVALID_TYPE.
(reduce_unary): Catch arithmetic expressions with invalid type.
(reduce_binary_ac): Likewise.
(reduce_binary_ca): Likewise.
(reduce_binary_aa): Likewise.
(eval_intrinsic): Likewise.
(gfc_real2complex): Source expression must be of type REAL.
* gfortran.h (enum arith): Add ARITH_INVALID_TYPE.
gcc/testsuite/ChangeLog:
PR fortran/107000
* gfortran.dg/pr107000.f90: New test.
