Thanks for the log, I'm trying to test it myself.

I'm not saying there is no problem at Wine but even MSDN discourages the mixed
use of overlapped and bytes sent pointer together.

...
Use NULL for this parameter if the lpOverlapped parameter is not NULL to avoid
potentially erroneous results. This parameter can be NULL only if the
lpOverlapped parameter is not NULL.
