Subject: [PATCH] Fortran: fix ICE in get_expr_storage_size [PR108421]
Date: Mon, 16 Jan 2023 21:38:55 +0100 [thread overview]
Message-ID: <trinity-1a5ca55f-e1cb-417f-9f67-59b39c16bc64-1673901535696@3c-app-gmx-bs50> (raw)
[-- Attachment #1: Type: text/plain, Size: 296 bytes --]
Dear all,
here's an obvious patch for an ICE-on-invalid where we missed
a check that we actually have an integer length before trying
to extract a usable value.
Regtested on x86_64-pc-linux-gnu.
I intend to commit it to mainline within the next 24h unless
there are comments.
Cheers,
Harald
