Occasionally I need  a core dump if testing goes wrong.
Boost test have the following option
------------
Parameter: catch_system_errors
 Allows to switch between catching and ignoring system errors (signals).
 Command line formats:
   --[no_]catch_system_errors[=<boolean value>]
   -s[ <boolean value>]
-------------------
I never managed to get short options to work and has to search for a long option
exact name.

Neither  '-s no',  '-s false' ,  -sno  with or without quotes are not accepted.

examples
-----
$ test_app -s no

Boost.Test WARNING: token "no" does not correspond to the Boost.Test argument
                    and should be placed after all Boost.Test arguments and the -- separator.
                    For example: test_app --random -- no
------
$ test_app "-s no"

Invalid separator for the parameter catch_system_errors in the argument -s no

Is it a known bug?
