memory corruption #282
Description
I tried using this in my VM.
I used this example and got memory corruption.
extern crate bdwgc_alloc;
use bdwgc_alloc::Allocator;
use std::alloc::Layout;
#[global_allocator]
static GLOBAL_ALLOCATOR: Allocator = Allocator;
fn main() {
unsafe { Allocator::initialize() }
loop {
unsafe { std::alloc::alloc(Layout::from_size_align(2 ^ 8, 8).unwrap()) };
}
}Weird things started happening like printing string literals lead to stuff like
