Reduced test case

Reduction of the Flickr URL.  The MallocDebug output has changed to a nastier
error, and Safari crashes while loading the page (under MallocDebug or gmalloc
only):

libMallocDebug[Safari-3622]: Target application (pid 3622) attempted to read
address 0x5555557d, which can't be read.
libMallocDebug[Safari-3622]: MallocDebug can't do anything about this, so the
app's just going to have to be terminated.
libMallocDebug[Safari-3622]: *************************************************
libMallocDebug[Safari-3622]: THIS IS A BUG IN THE PROGRAM BEING RUN UNDER
MALLOC DEBUG,
libMallocDebug[Safari-3622]: NOT A BUG IN MALLOC DEBUG!
libMallocDebug[Safari-3622]: *************************************************

Running the test case once under DumpRenderTree with guard malloc also causes a
crash.  Crash log coming up next.
