The construction is `@nogc`, but apparently depends on the `typeid(StackTrace)` monitor having been allocated already, i.e., a previous `StackTrace` construction. So pre-allocate a dedicated `Mutex` in the module constructor to make the `StackTrace` construction really `@nogc`. `druntime/test/allocations/src/alloc_from_assert.d` then passes on Windows again (not tested by DMD, but by LDC). While at it, also prevent `InvalidMemoryOperation` errors when trying to print exceptions within finalizers - by not resolving anything (=> empty printed trace), as resolving currently heavily depends on the GC. https://github.com/dlang/dmd/pull/14901 --
