Looks like this is a different issue. I have now linked against
OpenSSL instead of WinSSL and am experiencing the same behaviour. It
seems to be somehow related to a race condition because if I set a
breakpoint at http.c:1355 -
https://github.com/bagder/curl/blob/master/lib/http.c#L1355 - and
simply step through it, it works.
I hope to be able to invest some personal time over the weekend to
look into it more closely.
The application uses the multi interface using custom timer, read,
write and socket functions but since everything works w/o SSL and they
don't seem to be called during SSL handshake I'll go out on a limb and
say it's not due to their implementation.

All the best
Marcus
