--- Comment #4 from Stefan M Freudenberger <stefan at reservoir dot com> ---
My original example involved a MEM with a constant offset, and yielded an ICE:

internal compiler error: tree check: expected integer_cst, have
addr_space_convert_expr in decompose, at tree.h

Maybe I misinterpreted what type to expect for the operands of the MEM, and
hence constructed a bad example. I'll try to come up with an example that shows
the ICE.
