Subject: [Patch, Fortran] PR 55983: [4.7/4.8 Regression] ICE in find_typebound_proc_uop, at fortran/class.c:2711

Hi all,

here is a close-to-obvious patch for an ICE-on-invalid regression. It
removes as assert, which is reasonable for valid code but can fail
under error conditions (as the PR shows), and replaces it with an
equivalent IF clause.

Regtested on x86_64-unknown-linux-gnu. Ok for trunk and 4.7?

Cheers,
Janus
