#11288: Redundant std::string allocations in filesystem error handling code
--------------------------------+--------------------------
 Reporter:  yevhen.ivannikov@…  |      Owner:  bemandawes
     Type:  Bugs                |     Status:  new
Milestone:  To Be Determined    |  Component:  filesystem
  Version:  Boost 1.57.0        |   Severity:  Optimization
 Keywords:                      |
--------------------------------+--------------------------
 During performance profiling of our product it was identified that many
 std::strings allocations are coming from filesystem error handling code.

 The error handling code dynamically allocates std::string instances to
 store error messages, however when non-throwing API is used the strings
 are just redundant. Unnecessary allocations can be easily avoided by
 passing in const char*.

 Please find the patch attached.
