Bug ID: 92428
Summary: Crash on conflicting types
Product: gcc
Version: 8.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: dpotapov at gmail dot com

crash report
The following 4 lines of C code crashes the GCC compiler.
============================
enum Foo;
typedef unsigned Foo;
enum Foo foo(void);
Foo foo(void){ return 0; }
============================
I report it against gcc 8.1.0, but I have tried a few other versions, and all
of them crashed in the similar way (see crash.txt)
The program is incorrect, because the `foo` function declared as returning a
different type. So the expected behavior would be an error message:
enum.c:4:5: error: conflicting types for 'foo'
