--- 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
