+I'm quite sure this is a bug in valgrind.  The following simple
+program triggers the error:
+
+#include <new>
+
+int main(int, char**)
+{
+  int* foo = new(std::nothrow) int();
+  delete foo;
+
+  return 0;
+}
+
+It works fine when replacing new(std::nothrow) with the normal new.

+I just had a look at the libstdc++-v3 headers and found this:
+
+void operator delete(void *, const std::nothrow_t&) throw();
+
+So the std::nothrow overload does exist for delete as well -- but the
+compiler (g++ 3.2.1 here) doesn't accept it for some reason.  Well
+it's quite useless anyway since it has the same empty throw()
+signature as the normal delete.
+
+Since the nothrow variants of new/delete use the same memory
+allocation pool as the throwing ones there is no reason to disallow
+mixing them.  Therefore I would still regard this as a valgrind bug.

 h2defs.py is not part of gtkmm. Reassigning.

+------- Additional Comments From james daa com au  2002-11-16 06:04 -------
+Murray: when reassigning accross product boundaries, use "reassign bug
+to owner of selected component".  Otherwise I get no notification (you
+still own the bug).
+
+Tassos: h2def.py is not intended to create a fully correct defs file.
+ Quite often the resulting defs file will need some additional
+tweaking to add some information that could not be derived from the
+header.
+
+Working out what functions are constructors and what aren't is one
+such thing that can't always be deduced.  It seems that the current
+heuristics result in more correct defs entries than incorrect ones.
+
+If your tools can't handle (is-constructor-of "...") lines, then that
+is a bug in your tools (it has been in all the drafts of the current
+defs spec).  If the information is not of any use for you, then your
+tool should be ignoring it.
+
+I will leave it up to murray to close this if appropriate.
