Bug#512275: gcc-4.1 ICE on mixing typedef and enum names

[Marko Mäkelä <msmakela@gmail.com>]

Package: gcc-4.1
Version: 4.1.1-21
Severity: minor

This three-line test program will trigger an internal compiler error
when compiled with gcc -c /tmp/ice.c:

typedef enum { a } b;
extern enum b c;
int d(void) { return (c != a); }

/tmp/ice.c: In function ‘d’:
/tmp/ice.c:3: internal compiler error: in create_tmp_var, at gimplify.c:410

The bug has apparently been fixed by upstream, because GCC 4.3.2-1 on
Debian Lenny AMD64 duly flags the error:

bar.c: In function 'd':
bar.c:3: error: 'c' has an incomplete type
