The command argument when -x is present is a regular expression parsed
according to the rules in re_format(7).  'libsigc++' is indeed an
invalid regular expression according to those rules.  Try
'libsigc[+][+]' or 'libsigc\+\+' instead.

The characters

+  * . ? [ ] |

are all syntactically significant inside regular expressions and need
special treatment if you want to match one of them literally.  (Your
second case probably isn't doing exactly what you think it does, as it
will match:

    libsigc
    libsigcc
    libsigccc
    libsigcccc

etc.)

	Cheers,

	Matthew
