--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I'd say this is a Fortran FE bug.
The reason this ICEs is that the inliner emits 10 = 11; statement (with
INTEGER_CST on lhs), but that happens because myint PARM_DECL is TREE_READONLY,
which looks wrong when it clearly is assigned to.
The setting of TREE_READONLY happens in trans-decl.c:
2330 /* All implementation args are read-only. */
2331 TREE_READONLY (parm) = 1;
That looks just wrong at least for some f->sym->attr.value dummy arguments ==
PARM_DECLs, perhaps all?
