11905	"Exception ""character conversion failed"" when omitting argument"	Thibaut Lepage <dourak@…>	Vladimir Prus	"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
