#9218: Invalid pointer dereference on MSVC debug builds
--------------------------------------+--------------------------
 Reporter:  Gavin Lambert <gavinl@…>  |      Owner:  timblechmann
     Type:  Patches                   |     Status:  new
Milestone:  To Be Determined          |  Component:  lockfree
  Version:  Boost 1.53.0              |   Severity:  Problem
 Keywords:  windows msvc debug        |
--------------------------------------+--------------------------
 This is rare (so far only observed with race detection simulation), but
 due to the MSVC DebugCRT initialising "new" allocated memory to 0xCC
 instead of 0x00 the queue will miss a null pointer check in a particular
 race condition and try to dereference 0xCCCCCCCC.

 If you're interested I could probably get a log of the exact sequence of
 operations that leads to this error, but it's pretty wordy.
