The following testcase triggers an ICE since GCC 4.0.0:
==========================================
void foo(void (*p)(int n, int x[n])) {}
==========================================
bug.c: In function 'foo':
bug.c:1: internal compiler error: in make_decl_rtl, at varasm.c:1005
Please submit a full bug report, [etc.]
I'm not sure whether the code is invalid as an extension or not.
void bar(int n, int x[n]) {}
is accepted as well as
void foo(void (*p)(int n, int x[n]));
The C++ frontend rejects it, see also

------- Comment #1 from pinskia at gcc dot gnu dot org 2006-09-03 06:03 -------
Confirmed, this works just fine with typedefs:
typedef void (*type1)(int n, int x[n]);
void foo(type1 p){}
So we have a problem by looking at some parts of the function declation:
SAVE_EXPR <n>;
