[Opencxx-users] [OpenC++ Core] core dump while walking through valid code

[Altac E. <al...@ya...>]

Hi,
FYI, the 'elaboration-test-glue' test program core
dump when fed with the following code :

class A {
  void f() {
    int x(*this);
  }
};

* I've reduced the test case as much as possible, but
it's originating from STL stuff.
* The occ-core source is taken from CVS HEAD, today.
* The backtrace is :

I'm not familiar enough with OpenC++ to investigate
further.
