Hi,

I tried to use a program that uses this library:

https://github.com/microsoft/mimalloc

this library uses a precompiled dll file named mimalloc-redirect.dll
this dll can not load under wine since it have at least one missing dependency
RtlQueryEnvironmentVariable

this dll loads fine under winodws.

compiling the samples/test from this project will give you the test program. 
even a simple program that just calls LoadLibrary will show the problem.
