--- Comment #7 from Martin Liška <marxin at gcc dot gnu.org> ---
New reduced test-case:

$ cat 1.ii
namespace xercesc_2_5 {
class MemoryManager;
class XMemory {
  void *operator new(unsigned long, MemoryManager *);
};
class MemoryManager {
public:
  virtual void *allocate();
};
void *XMemory::operator new(unsigned long, MemoryManager *manager) {
  long headerSize(sizeof(MemoryManager));
  void *block = manager->allocate();
  return block + headerSize;
}
} // namespace xercesc_2_5

$ cat 2.ii
namespace xercesc_2_5 {
class MemoryManager;
class XMemory {
public:
  void *operator new(unsigned long, MemoryManager *);
  void operator delete(void *, MemoryManager *);
};
class XMLPlatformUtils {
public:
  static MemoryManager *fgMemoryManager;
};
class ValueStackOf : public XMemory {
public:
  ValueStackOf(int, bool);
};
class XPathMatcherStack {
  XPathMatcherStack();
  ValueStackOf *fContextStack;
};
XPathMatcherStack::XPathMatcherStack()
    : fContextStack(new (XMLPlatformUtils::fgMemoryManager)
                        ValueStackOf(8, XMLPlatformUtils::fgMemoryManager)) {}
} // namespace xercesc_2_5
