Is the shader source for this application available?

Something strange is happening here.  The assertion that is hit occurs while
the compiler is trying to constant-fold int-to-float operations.  The type of
the source should be int, but it's not.

Can you run this application in GDB and 'up' until GDB says it's in
ir_expression::constant_expression_value.  Then 'print op[0]->type->name' and
'print op[0]->type->base_type'.
