This is with today's sources, so unrelated to the previously fixed
PR 21789 even though the error message is the same.
With attached code, I get this:
spec/src> c++ -O2 -march=pentium4m -msse2 -ftree-vectorize
auto_derivative_function.ii
auto_derivative_function.ii:6859: warning: ‘__malloc__’ attribute ignored
auto_derivative_function.ii: In member function ‘void
AutoDerivativeFunction<dim>::gradient_list(const std::vector<Point<dim>,
std::allocator<Point<dim> > >&, std::vector<Tensor<1, dim>,

auto_derivative_function.ii:32743: internal compiler error: tree check:

This is most likely related to PR 21155 which is another bug with the same ICE.

I don't know -- the failure appears in a completely different place. I see
this particular ICE on at least half a dozen of my files, but I'll be happy
holding off finding a reduced testcase until the other PR is fixed.

Much shorter testcase
I attach another testcase that I managed to get down to approximately 10kloc.
It is only standard include files now, so shouldn't be too hard to reduce
further (if only I had more time...)
It presently gives me this:
spec/src> c++ -O2 -march=pentium4m -msse2 -ftree-vectorize -c x.ii
x.ii:1489: warning: ‘__malloc__’ attribute ignored
x.ii: In constructor ‘X::X()’:

var_decl in verify_ssa, at tree-ssa.c:750

I tried compiling x.ii on power-pc and couldn't reproduce the problem.
I don't know if this means that the problem goes away with recent
patches or that it only occurs when vectorizing on pentium. I currently
don't have the ability to build and test on pentium.

I tried on powerpc-apple-darwin and on i686-pc-linux-gnu - couldn't reproduce
the failure

Another testcase possibly, that triggers the fault on 20050605 with parameters
-march=pentium4 -O3 -ftree-vectorize, but not with -O2 or -O1. Bug 21933 seems
related but doesn't trigger with -O3 or -O2, but does with -O1 (the testcase in
this bug also doesn't use standard includes, so may be easier to track down)
#include <vector>
const int COUNT = 4;
struct A {
public:
A() {
for (int i=0; i<COUNT;++i) x1[i] = 0;
}
void * x1[COUNT];
};
struct B : std::vector <A> {
void p1() {
clear();
insert(end(), A());
}
};
struct C {
B c1;
void p2();
};
void C::p2() {
c1.p1();
}

correction - can't reproduce the failure on powerpc,
but I do see the ICE on i686-pc-linux-gnu with both testcases (from comments #4
and #7). (I couldn't see the ICE before because I was accidently trying with a
compiler configured with disable-checking before)

All three testcases (from comment #1, #4, and #7)
got fixed by Keith's patch.
