You are right. Sounds like not a regression.
Sorry

Actually, I have some 3.2 version and that ICEs too (branched in 2002):
pr91193.c:2: `a' redeclared as different kind of symbol

pr91193.c:1: previous declaration of `a'
pr91193.c:2: confused by earlier errors, bailing out

Why do you think this is a regression?
/usr/src/gcc-test/obj/gcc/cc1.9 pr91193.c
 a

pr91193.c:2: error: ‘a’ redeclared as different kind of symbol
pr91193.c:1: error: previous declaration of ‘a’ was here
pr91193.c: In function ‘a’:
pr91193.c:2: internal compiler error: tree check: expected class ‘type’, have
‘declaration’ (function_decl) in grokdeclarator, at c-decl.c:3788

I don't have anything older than r9.

And slightly cleaner
typedef int a;
void a() a b;
also ICEs.
