--- 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.
