Given the following C code: struct Foo* foo(void); typedef struct Foo { int x; } Foo; foo.c(1): Error: struct `foo.Foo` no size because of forward reference The compiler then segfaults. Interestingly, changing it to struct Foo* foo(void); struct Foo { int x; } Foo; Has the same behavior.

Another case that triggers the same message and ICE: typedef struct Foo Foo; typedef struct Foo { int x; } Foo;
