False positive: Opposite inner 'if' condition leads to a dead code block.

[Jean Porcherot]

This code generates what is likelly a false positive:

#include <string>

#define TYPE_1 "a"
#define TYPE_2 "b"
#define TYPE_3 "c"

void Restore( const std::string& channel )
{
    if ( channel == TYPE_1 )
    {

    }
    else if ( channel == TYPE_2 || channel == TYPE_3 )
    {
        // common code for TYPE_2 and TYPE_3

        if ( channel == TYPE_2 ) // reporting "warning : Opposite inner 'if' condition leads to a dead code block."
        {
            // specific code for TYPE_2
        }
        else if ( channel == TYPE_3 )
        {
            // specific code for TYPE_3
        }
    }
}
