selectively disable validation in compile-fail where appropriate. cargo test now passes :) 2017-08-02 17:35:44 -05:00			`// Validation makes this fail in the wrong place`

change the block and stmt position after a function call returns previously we moved to the target block before calling a function, so when inspecting the stack, it appeared as if we were in the first statement of the next block. 2016-07-06 10:55:05 -05:00			`f() //~ ERROR: tried to treat a memory pointer as a function pointer`
