--- Comment #7 from Michael Karcher wine@mkarcher.dialup.fu-berlin.de 2011-03-30 16:09:30 CDT --- No, bug 13706 has never been fixed. As was stated in that bug, it is an uninitialized memory read (in the application). Depending on compiler and library versions on the system, the contents of that uninitialized memory location may happen to be 0, avoiding the crash, be some kind-of valid pointer value causing strange behavior or be an non-NULL invalid pointer causing the crash.
