             Bug #: 31512
           Summary: 'Movavi video converter 3D' crashes in RegSetValueExW
           Product: Wine
           Version: 1.5.11
          Platform: x86
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: advapi32
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: dank at kegel.com
    Classification: Unclassified


After doing 'winetricks wmp9' to work around bug 31511, the next problem
is another crash on startup:

Unhandled exception: page fault on read access to 0xffffffff in 32-bit code
(0x7ea5adff).
Backtrace:
=>0 0x7ea5adff RegSetValueExW+0xcf() in advapi32 (0x0a9faea8)
  1 0x2006d01b in pkgmanager (+0x6d01a) (0x7ea5b390)

Turns out they called RegSetValueExW() with data=1 (i.e. they passed
by value instead of reference), and on Windows, this returns a nice error
code instead of crashing.

I have a test and a patch, will send shortly.
