This code here has a potential issue:
rust/compiler/rustc_mir_transform/src/coroutine.rs
Lines 1967 to 1977 in 010f394
If the Box has a custom allocator, then that will not be checked at all. So whatever check_must_not_suspend_ty is used for, it ignores anything stored in custom allocators.
It seems like this is just for a lint, so this is probably not critical, but I guess should still be fixed.
Cc @cjgillot -- not sure whom else to ping for coroutine state machine transform things?
