     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  optional
  Version:  Boost 1.49.0      |   Severity:  Problem
 Keywords:                    |
------------------------------+-----------------------
 For example:

 boost::optional<char> oa = boost::in_place<double>(0); // type-checks but
 results in runtime undefined behavior, placement new of double in a buffer
 of size char.
