- Reply-to: gcc-bugzilla at gcc dot gnu dot org
The following invalid code snippet triggers an ICE in the C frontend since
at least GCC 2.95.3:
=============================
void foo(struct A a) {}
void foo() {}
=============================
bug.c:1: warning: 'struct A' declared inside parameter list
bug.c:1: warning: its scope is only this definition or declaration, which is
probably not what you want
bug.c:1: error: parameter 1 ('a') has incomplete type
bug.c:2: error: redefinition of 'foo'
bug.c:1: error: previous definition of 'foo' was here
bug.c: In function 'foo':
bug.c:2: internal compiler error: tree check: expected class 'type', have
'exceptional' (error_mark) in store_parm_decls_oldstyle, at c-decl.c:6375
Please submit a full bug report, [etc.]
