http://bugs.winehq.org/show_bug.cgi?id=28423

Summary: ImmGetDescriptionW() from imm32 crashes with certain
                    parameters
           Product: Wine
           Version: unspecified
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

Created an attachment (id=36436)
 --> (http://bugs.winehq.org/attachment.cgi?id=36436)
The test program I did.

When a program calls ImmGetDescriptionW(NULL,NULL,direction), it crashes
instead of returning a direction and the size of it in characters, here is a
test program in the attachments and its source code.

This bug can be solved by adding this or something to allcate memory to imm32,
try it on both windows.

Also, it only occurs in a pointer, not on a finite empty array.
