     Type:  Bugs                         |     Status:  new
Milestone:  To Be Determined             |  Component:  program_options
  Version:  Boost 1.55.0                 |   Severity:  Problem
 Keywords:                               |
-----------------------------------------+-----------------------------
 When using a long option name like "external-device", if there is a
 problem, the name of the option in the error message is printed as "--
 device" instead of "--external-device".  This is due to the implementation
 in error_with_option_name::get_canonical_option_name() in the
 value_semantic.cpp file.  It calls strip_prefixes() when assigning the
 value to original_token.  But strip_prefixes() simply uses
 find_last_of("-/"), which finds the dash within the option name and
 incorrectly uses the following character as the start of the option name.

 I don't know the proper fix to apply in order to not cause errors in other
 uses of these functions.
