Advancing beyond end in AstGen.advanceSourceCursor #13714
Description
Zig Version
0.11.0-dev.386+deda6b514
Steps to Reproduce and Observed Behavior
Create main.zig containing
pub fn main() !void {
var image: [1]u8 = undefined;
_ = @shlExact(@as(u16, image[0]), 8);
}
and run zig2 build-exe main.zig. It panics in
thread 4551387 panic: reached unreachable code

if (!ok) unreachable; // assertion failure

Expected Behavior
To compile without error. Works with zig 0.10 and 0.9.1.
