Update for changes in rustc. 2016-08-27 01:44:46 -06:00			`fn main() {`
call error location was fixed by rustup 2020-03-21 12:52:23 +01:00			`fn f() {}`
forbid calling functions through pointers of a different type 2016-06-14 10:34:54 +02:00
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 17:55:05 +02:00			`let g = unsafe {`
forbid calling functions through pointers of a different type 2016-06-14 10:34:54 +02:00			`std::mem::transmute::<fn(), fn(i32)>(f)`
			`};`
