Memory error for C++ runtime

[Andy]

 I have compiled pascal.g4 by java -jar antlr-4.7.2-complete.jar -Dlanguage=pascal.g4
(I must change bool to bool_)
Sources compiled.
But when run: is error at line dfa::Vocabulary pascalLexer::_vocabulary(_literalNames, _symbolicNames); (L212)
I can't better locate because I don't have sources of runtime C++.
Where are available sources of C++ runtime?

[Andy]

OK, I see https://github.com/antlr/antlr4/tree/master/runtime/Cpp/runtime

Is error in version 4.7.2
Vocabulary::Vocabulary(const std::vector<std::string> &literalNames, const std::vector<std::string> &symbolicNames)
: Vocabulary(literalNames, symbolicNames, {}) {
}

Vocabulary::Vocabulary(const std::vector<std::string> &literalNames,
  const std::vector<std::string> &symbolicNames, const std::vector<std::string> &displayNames)
ERROR--------------->  : _literalNames(literalNames), _symbolicNames(symbolicNames), _displayNames(displayNames),
    _maxTokenType(std::max(_displayNames.size(), std::max(_literalNames.size(), _symbolicNames.size())) - 1) {
  // See note here on -1 part: https://github.com/antlr/antlr4/pull/1146
}

In last version is error:

In https://github.com/antlr/antlr4/blob/master/doc/cpp-target.md is obsolete
using namespace org::antlr::v4::runtime; whereas need using namespace org::antlr4;

Runtime error was for VS2015, but for VS2017 is OK.
Error - static initialization of vector?

Hi Andy,

In your first message you wrote the parser compiled, now you present a linker error. I don't have my Windows machine at hand atm. and it compiles with clang (in XCode), so I'm a bit clueless. However, it is probably something simple. A not exported type or a signature changed or something like that. Can you try to figure that out?

Actually only `using namespace antlr4;`. I'll take care of that, thanks.

Maybe it is connected to c++ version? In C++17 is Ok, else we have static initialization of vector.
