 sigsegv by uninitialized local variable with -check_media patch_lba0="on"
 The fix is worthwhile, because the bug is nasty albeit rarely occuring.
 I encountered a SIGSEGV by dereferring NULL, but it could have been any
 other random stack value instead. So the bug has some potential.
 The risk of introducing regressions is low.
