Hi Dan,
The following warning is caused by the generated code for non-encapsulated unions not setting _StubMsg.MaxCount before calling the relevant phase function. However, looking in detail at this bug brings up a few other issues with the code which need to be fixed.

The following warning is caused simply by a missing call to _StubMsg.pfnFree in the generated code:
- 24 bytes in 2 blocks are definitely lost
- at malloc (vg_replace_malloc.c:207)
- by MIDL_user_allocate (server.c:53)
