--- Comment #11 from Michel Dänzer <michel@daenzer.net> ---
I run into the assertion failure below in the GLSL compiler. That should be
addressed first.

test2: ../../../src/glsl/ir_validate.cpp:436: virtual ir_visitor_status
{anonymous}::ir_validate::visit_leave(ir_expression*): Assertion
`ir->operands[0]->type == ir->operands[1]->type' failed.

Program received signal SIGABRT, Aborted.
