0 instead of nullptr as default argument
I don't think this is a duplicated of 51196.
In the following example, the locations about the uses of 0
instead of nullptr are misleading: none point to the real
issue, but they point to where the default argument was used.
$ g++-mp-4.8 -Wzero-as-null-pointer-constant -c /tmp/foo.cc
/tmp/foo.cc: In constructor 'bar::bar()':
/tmp/foo.cc:10:9: warning: zero as null pointer constant
[-Wzero-as-null-pointer-constant]
/tmp/foo.cc: At global scope:
/tmp/foo.cc:15:27: warning: zero as null pointer constant
