Program halt when constructing std::string

Question

In the following code, when constructing the string url, the execution halts. No error, the execution doesn't stop, it just hangs there, and I can't press step over. Everything seems fine in the debugger, no nullpointers, the baseURL is set properly. RapidXML's value() function returns char*.

Am I missing something?

With Eclipse Indigo on Ubuntu 12.04

    rapidxml::xml_node<> *galleryNode = myNode->first_node("gallery");
    std::string baseURL = galleryNode->first_attribute("url")->value();
    galleryNode = galleryNode->first_node("filename");
    while ( galleryNode != NULL )
    {
        std::string url(baseURL);
        url.append(galleryNode->value());
        gallery.AddImageUrl(url);
        galleryNode = galleryNode->next_sibling();
    }

The cause was the python enabled gdb in eclipse. I downloaded it with svn, then altered the gdbinit file. Viewing variables was much easier while debugging, but apparently it has quite annoying side effects.
