Bug ID: 106764
Summary: ICE on invalid code in tree check: expected
function_type or method_type, have error_mark in
gimplify_call_expr, at gimplify.cc
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: k.even-mendoza at imperial dot ac.uk
Target Milestone: ---
This code leads to ICE in GCC-12 and 13:
===
(*a)();
b(){a()} a;
===
We are doing a study about compiler fuzzers. We got this from one of the tools.
I wonder if such a bug is interesting even if the program is chopped in the
middle?
