Hmm, I didn't expect you to do both -D_GLIBCXX_DEBUG and VG (though it's still a valid thing to do). I expect you'll get similar VG errors even without -D_GLIBCXX_DEBUG > ==20939== Invalid write of size 4 > ==20939== at 0x40D557C: > __gnu_debug::_Safe_sequence_base::_Safe_sequence_base() (safe_base.h:179) > ==20939== by 0x40D5724: > __gnu_debug::_Safe_sequence<std::__debug::list<gdcm::Element, > std::allocator<gdcm::Element> > >::_Safe_sequence() (safe_sequence.h:103) > ==20939== by 0x40D84B5: > std::__debug::list<gdcm::Element,std::allocator<gdcm::Element> > >::list(std::allocator<gdcm::Element> const&) (list:103) > ==20939== by 0x411C563: gdcm::Document::Document() (gdcmDocument.cxx:58) This isn't complete VG message. There should be some stuff following the above lines, which tells you what address is being written, and what VG knows about that address. Unfortunately that info (which you presumably trimmed) is the key to understanding what the error means. > Is there a document somewhere describing what this means and/or how > to fix my code. You may try posting your entire error message to the valgrind-users mailing list at https://lists.sourceforge.net/lists/listinfo/valgrind-users Before you do that, you should check that this is not a "glitch" in your system setup: write a trivial program that uses std::list correctly, compile it the same way and run it through VG; it should show no errors. Now "inject" some bugs into it, and see what comes out. Cheers, -- In order to understand recursion you must first understand recursion.
