#15261 shows us that Windows can crash if you pass in an invalid file handle to Windows POSIX-y functions. We should ensure that functions which accept path-as-an-int-fd guard against this where necessary. I propose a macro, something like #ifdef MS_WINDOWS #define FD_GUARD(fd) (_PyVerify_fd(fd) ? (fd) : INVALID_HANDLE_VALUE) #else #define FD_GUARD(fd) (fd) #endif

#ifdef MS_WINDOWS
#define FD_GUARD(fd) (_PyVerify_fd(fd) ? (fd) : INVALID_HANDLE_VALUE)
#else
#define FD_GUARD(fd) (fd)
