Recursion hell

[DutchGhost]

Not sure if this is really a bug or not...

fn recur() [@maxValue(usize)]u8 {
    return recur();
}

pub fn main() void {
    @import("std").debug.warn("starting ...\n");
    
    var loophole = recur();

    @import("std").debug.warn("{}\n", loophole);
}

Compiles fine, but once runned, nothing gets printed to the screen. I expected it to at least print 'starting ...' to the screen, and then stackoverflow. This happens on build-exe and build-exe --release-fast.

On my machine I dont see any segfault or stack overflow message, but maybe that's just my machine.

https://bugs.llvm.org/show_bug.cgi?id=965 might be the root of this?

I see a segfault:

$ ./test
Segmentation fault

Can be closed then. I suppose Windows doesn't care about segfaults?

OK, at least we got issue #1424 out of it. I believe the problem has to do with creating an array that large and overflowing the stack, rather than the recursion.
