screenshot of the reported error.
In the code fragment bellow we getting following error:
Called C++ object pointer is null (within a call to 'regex_match')
Code:
std::regex reg("(.*)(/)");
std::string facet = "test";
if( !(std::regex_match(facet, reg) ) )
{
facet += path_sep;
}
I have also attached the screenshot for reported error.
We are using Xcode 8.3.2 Analyze</pre>
