I had a very similar (if not the same) problem, see
Excerpt from that message:
"[...] I do receive an error [in the Windows eventlog]
when rrdtool fails to create a graph. Windows informs me that rrdtool has
crashed, with the error code 0xc0000417. This error code stands for
STATUS_INVALID_CRUNTIME_PARAMETER, with the explanation that "#An invalid
parameter was passed to a C runtime function."
Reading WIN32-BUILD-TIPS.txt, I found this:

So, to me it looks like instead of the included strftime, the Windows
version of strftime is used, which doesn't know about %V."
