Bug ID: 48059
           Summary: IMVU Social Network Client hangs
           Product: Wine
           Version: 4.19
          Hardware: x86
               URL: https://secure.imvu.com
                OS: Linux
            Status: NEW
          Keywords: regression
          Severity: normal
          Priority: P2
         Component: kernel32
          Assignee: wine-bugs@winehq.org

   Regression SHA1: 3b002685fe18ca3985af744d8f147f29b2c588f0
      Distribution: ---
There's clearly some nonsense going on with hooking. The game tries to call
kernel32.OutputDebugString(), which, instead of then executing Wine's
implementation, instead goes on to write the message to a file in the game's
directory, repeatedly, in a loop.
Reverting 3b002685f fixes this. Changing kernel32's spec file to forward to
kernelbase instead of using an import thunk also fixes this. What's confusing
me is I can't figure out how the hooking is actually done. Tracing the code of
OutputDebugString(), both A and W versions, both from kernel32 and kernelbase,
never seems to show signs of hooking, i.e. it's entirely identical to the
version on disk.
Note that the application requires an email-based account to be created.
