This PR fixes the
StackFallbackAllocatorthat has been broken since #5064.I also added a test to prevent future regression.
This really only fixes it for cases where the fallback allocator is an allocator that was defined inside
heap.zigas it relies on access toreallocFnof the allocator itself. It probably needs a redesign to have it working with all allocators. If it's not too complex or someone is willing to point me in the right direction I don't mind implementing that as well.ps: Any feedback is welcome, really.
