#11905: Exception "character conversion failed" when omitting argument
---------------------------------------+-----------------------------
 Reporter: Thibaut Lepage <dourak@…> | Owner: vladimir_prus

Milestone: To Be Determined | Component: program_options
  Version: Boost 1.60.0 | Severity: Problem

 Hello,

 The minimal example I attached simply assigns the value of the optional
 parameter -i to an int.
 When the parameter is given (./a.out -i 42), the program exits normally.
 But if I omit the parameter (./a.out), then the exception "character
 conversion failed" is raised.
 It doesn't matter whether the option is "required" or not, or whether a
 default value is given.

 Configuration for which I found the bug:
 CentOS: 7.2
 gcc: 4.8.5
 boost: both 1.60.0 and 1.54.0

 Configuration for which the bug does not occur:
 Linux Mint 17.2
 gcc 4.8.4
 boost 1.54.0

 Regards,
 Thibaut Lepage
