      Description

      using r42356, l33t.exe from http://ryanross.net/leet/ and windows mfc42.dll
      I launched l33t.exe type in some text to convert to leet and hit the translate button, the application is now hung. tested in vbox 3.0.0 r49315

      I preceded to break into kdbg to analyze the issue.
      You might notice that kdbg thread list command shows an eip for the thread, but the backtrace command does not.

      PuTTYEntered debugger on embedded INT3 at 0x0008:0x808c06f6.
