#9147: uninitialized std::tm

     Type:  Bugs                         |     Status:  new
Milestone:  To Be Determined             |  Component:  chrono
  Version:  Boost 1.54.0                 |   Severity:  Cosmetic
 Keywords:                               |
-----------------------------------------+----------------------
 The struct std::tm seems uninitialized, or have possibly uninitialized
 members in a few places.

 For example in https://svn.boost.org/trac/boost/changeset/85610


 The most common patterns in boost seems to be to do

 {{{
   std::tm x;
   std::memset(&x, 0, sizeof(x));
 }}}

 which seems good.

 Some different/missing/suspicious initializations:

 {{{
 boost/log/detail/decomposed_time.hpp:    std::tm res = {};
 boost/chrono/io/time_point_io.hpp (possibly several)

 util/gregorian.cpp - the gregorian_calendar class members

 boost/date_time/microsec_time_clock.hpp
  (std::tm curr possibly not fully initialized)

 }}}
