Are you compiling libcurl yourself or are you using a pre-built DLL? As I
recall, Windows has a problem when using stdio when two different CRTs are
involved, one for libcurl and one for your application. The two versions may
have incompatible structures, so creating a FILE* in your application with one
CRT and passing it to libcurl that uses it with another might not work.
If you don't want to compile your own libcurl, then you'll probably have to
install your own CURLOPT_DEBUGFUNCTION so you have complete control over which
functions are used to write to the log file.
