            Bug ID: 40222
           Summary: IMalloc(Spy)::Free nullptr
           Product: Wine
           Version: unspecified
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: ole32
          Assignee: wine-bugs at winehq.org
          Reporter: learn0more+wine at gmail.com
      Distribution: ---

Created attachment 53739
  --> https://bugs.winehq.org/attachment.cgi?id=53739
the binary triggering the bug.

Calling IMalloc::Free with a nullptr should not invoke the IMallocSpy.
(IMalloc_fnFree)

Bug encountered in ReactOS (Where the IMallocSpy implementation from wine is
used).
See: https://jira.reactos.org/browse/CORE-10903

Also verified on wine.
Attached binary invokes the invalid behavior on ReactOS and Wine, and not on
Windows.

(Run: `wine atl_apitest.exe CComHeapPtr`)
