[PATCH] PR fortran/103588 - ICE: Simplification error in gfc_ref_dimen_size, at fortran/array.c:2407

[Harald Anlauf]

Dear all,

using a bad expression as stride in a subsequent array section did
lead to an internal error which was directly invoked after the
failure.  We better return a failure code to let error recovery
do its expected job.

Regtested on x86_64-pc-linux-gnu.  OK for mainline?

Thanks,
Harald
