       CURLFORM_BUFFERLENGTH
              is used in combination with CURLFORM_BUFFER. The
              parameter is a long which gives the length of the
              buffer.

dataSize is an unsigned int, not a long like it should be. On 32-bit x86
Linux they're the same length, but on x86-64, they're not. That's probably
the problem right there.
