I can't find any libcurl docs anywhere that says setting CURLOPT_POSTFIELDS to
NULL is a good idea for any purpose.

CURLOPT_POSTFIELDSIZE overrides getting the size from the given pointer, did
you by any chance have that already set?

Since you didn't show us a complete example, I have trouble to see how this is
a bug in libcurl or if so, what the exact problem might be.
