Comment:

 Thanks for the report. libstdc++ was using memset to initialize the array
 of chars. In commit (master and develop branches):

 SHA-1: 5afad7cd0c5512016f9ad60e03c95e84a470ce17

 * Added optimization for types that can be value initialized with memset.

 Boost.Container uses memset with zero value to initialize several types
 including "char" values.
