--- Comment #1 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
The code compiles with gfortran configured with --enable-checking=release, but
segfault at run time. However if gfortran is configured with
--enable-checking=yes, I get
pr80255.f90:1:0:
program test
Error: conversion of register to a different size
VIEW_CONVERT_EXPR<struct __class__STAR_a>(_28);
MEM[(struct ftlany[0:] *)_29][_31].value = VIEW_CONVERT_EXPR<struct

Please submit a full bug report,
with preprocessed source if appropriate.
See <https://gcc.gnu.org/bugs/> for instructions.
I don't have the patience to look at the standard, but I am not sure the code
is valid.
