Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3

Code demonstrating problems.
Hi all!
ICE both in:
GNU Fortran (GCC) 9.2.1 20200307
and
GNU Fortran (GCC) 10.0.1 20200307 (experimental)
simplify_bound in simplify.c does not expect an AS_DEFERRED array.
Thank you very much.
Best regards,
José Rui

--- Comment #1 from kargl at gcc dot gnu.org ---
Quite silly to have an assert if compiler has already issued an error.

ICE on wrong code [PR94192].
The idea is not have another resolution of a pointer if an error has
occurred previously.

PR fortran/94192
* resolve.c (resolve_fl_var_and_proc): Set flag "error" to 1 if
pointer is found to not have an assumed rank or a deferred shape.
* simplify.c (simplify_bound): If an error has been issued for a
given pointer, one should not attempt to find its bounds.
