C Dynamically Linking To Tinyxml/tinyxml-2 Causes Segfault

[AntumDeluge]

I've been trying to use the XML parser tinyxml-2 (textproc/tinyxml2), but I can only link to it statically. If I try linking to the shared object my program crashes with a "segmentation fault" error.

Here are the compiling commands and application output:

$ ls
test.cpp   test.xml
$ g++ test.cpp -o test -ltinyxml2
$ ./test test.xml
Segmentation fault (core dumped)
$ g++ test.cpp -o test /usr/local/lib/libtinyxml2.a
$ ./test test.xml
Loading XML contents....
sword
Loaded.

Here are the contents of the source and XML file, just in case.

test.cpp:

#include <tinyxml2.h>
using namespace tinyxml2;

#include <iostream>
using namespace std;

int loadXML(char* filename) {
  XMLDocument doc;
  doc.LoadFile(filename);
  
  XMLElement* titleElement = doc.FirstChildElement("items")->FirstChildElement("item")->FirstChildElement("name");
  
  cout << titleElement->GetText() << endl;
  
  return doc.ErrorID();
}

int main(int argc, char* argv[]) {
  // Load XML contents
  cout << "Loading XML contents....\n";
  if (argc > 1) {
  loadXML(argv[1]);
  cout << "Loaded.\n";
  } else {
  cout << "Must specify an XML file... exiting.\n";
  return 1;
  }
  
  return 0;
}

test.xml:

<?xml version="1.0" encoding="UTF-8" ?>

<items>

Please let me know if anyone else is having the same problem. I have filed a bug report: PR 194375. I believe that the problem affects both textproc/tinyxml2 and textproc/tinyxml, though I have only tested it thoroughly with tinyxml2.

My system:

• FreeBSD 10.0-RELEASE r260789 amd64
• gcc/g++ 4.7.4 (FreeBSD Ports Collection)
