If this means that libc symbols are resolved to ucrtbase.dll.so, that sounds like a bug in the dynamic linker. We load dlls without RTLD_GLOBAL so their symbols should not be available for global resolution.
There seems to be something wrong with the Linux without-mingw build too. I've tested changing the "pow" function to "MSVCRT_pow" and it affects how often the function is called while running: wine nonexisting.exe
When the function was called pow it was called 2048. It was called 0 times after changing the name to MSVCRT_pow. It was also not called in mingw builds no mater how function was named.
