Well that's odd...

error[E0080]: Miri evaluation error: a raw memory access tried to access part of a pointer value as raw bytes
  --> $DIR/heap_allocator.rs:43:24
   |
43 |             assert_eq!((ptr.as_ptr() as usize) % align, 0,
   |                        ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Miri evaluation error: a raw memory access tried to access part of a pointer value as raw bytes

So calling the allocation function actually succeeds, but then later checking alignment does not.

Wow, MIRI_BACKTRACE makes everything just crazy slow, at least on Windows.

@oli-obk this build log looks like we are throwing and catching tons of Miri errors. That doesn't seem right.

Found it! There was a bug in the alignment we used for the system allocator (malloc and friends).

I expanded the heap_allocator test to cover this on all platforms now.
