#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.
