Compiler assert hit in DeallocateVariable

Hi, I've been working on updating to the svn build of AS, and I'm getting an assertion failure in asCCompiler::DeallocateVariable. It triggers when I use code like this:

class A {
	A() {}
	A(A@ other) {}
};

class B {
	B(A@ a) {
		A x(a);
	}
};

Which causes asASSERT(offset == 0x7FFF) to fail.

I commented out the assert and everything seems to be working fine, so I'm assuming for now that the assert is wrong. I do have some local changes to the angelscript source, but nothing that I can see that would cause this, so I'm hoping you're able to reproduce it. svn commit used is 2292.
