`fopen`/ `fclose` crash on Windows with DLLs loaded via LoadLibrary

[kylincaster]

Hi, I recently submitted a pull request that adds:

• Windows support for loading dynamic libraries via LoadLibrary
• Using @generated macro to simulate variadic C-style function templates (e.g., printf, printf!)

PR link: Add Windows DLL Support and Template-like Variadic Print Functions #70

While the core functionality works, there is one unresolved issue:

When calling standard C I/O functions like fopen and fclose via Windows dll api LoadLibrary, the program crashes.
Strangely, this does not happen when:

• Using Julia’s native ccall(:fopen, ...)
• Exporting LLVM IR and compiling into a standalone executable

This may be due to CRT linkage mismatches or buffering conflicts between different runtime contexts.
If anyone knows how to fix this CRT/runtime conflict, please help!

Cheers,
Kylin
