That's somewhat worrisome. So you have multiple instances
of the C runtime library active in the same app?
Maybe you're not unloading that dll gracefully enough.
Might be heap corruption. I wonder if Valgrind might be helpful.
I second the suggestion to post a minimal testcase.
Here's a link to a zip file that includes the prebuilt .exe and .dll
windows binaries that crash in wine. Plus the code.

So, again, the bug is that MSVCRT calls are failing when called from a
DLL that has been reloaded. If the calls come from a thread and if the
DLL is built with static MSVCRT runtimes.
There is no crash for the program in Windows.
I also tried rebuilding the code for winelib, and it doesn't appear to
have the same behavior. So the problem doesn't happen if Wine's MSVCRT
is used, only if a windows DLL that uses static MSVCRT linkage is reloaded.
