Loading C++ dll from C# executable with mimalloc

I am using a C# executable that loads a C++ dll with VS2019 msvc compiler (that also has dependencies on some other C++ dll's under my control). As soon as i enable mimalloc within C++ it crashes. See below.

I am correctly linking with mimalloc-override.lib and using
`#include `
It crashes directly when i try to load the C++ dll from within C#. This process is already working with both the default allocator and another custom allocator. Any clues what i am doing wrong? Or is this not supported?

Exception:
`Unhandled exception at 0x77252465 (ntdll.dll) in program.exe: 0xC0000005: Access violation reading location 0x00000000.`
when starting the program i'm getting the following callstack:

```
ntdll.dll!_RtlUnicodeToMultiByteN@20() Unknown
ntdll.dll!RtlUnicodeStringToAnsiString() Unknown

```

I think this is the C# callstack trying to load my C++ dll.

Start by reproducing the crash when the C# executable loads the C++ DLL with mimalloc-override.lib and mimalloc-new-delete.h enabled. Inspect the mimalloc-redirect32.dll frames in the provided loader call stack and compare behavior with the default and other custom allocators. Done means identifying the supported configuration or documenting the incompatibility and its cause.
