What steps will reproduce the problem?
In some code if you have an internal variable that is used for a default
argument, cppclean says it's not needed. E.g.:
static const char foo[] = "blablabla";
void f(const char * cstr = foo){}
int main()
{
f();
return 0;
}
What is the expected output? What do you see instead?
I expect cppclean to have no problems with this. Instead it says:
clean_test.C:1: unused variable 'foo'
What version of the product are you using? On what operating system?
I am using cppclean 0.2.5, on Mac OSX 10.9.5.
Please provide any additional information below.
clang++ with -Wextra (but not with just -Wall) also complains that the variable
is not needed.
It's possible I'm misunderstanding what the warning is trying to tell me. I am
interpreting "not needed" as "you could delete this line and it wouldn't break
anything". Clearly removing that line does break the code (I even tried it
with clang++ just to be sure).
