#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.
