Subject: [Bug c++/22238] New: [4.0/4.1 regression] '#'obj_type_ref' not supported by dump_expr
Date: Wed, 29 Jun 2005 23:21:00 -0000	[thread overview]
Message-ID: <20050629232130.22238.reichelt@gcc.gnu.org> (raw)

Since GCC 4.0.0 the compiler issues a hosed error message for the
following invalid code snippet:

======================================
struct A
{
  virtual void foo();
  void bar() { if (foo()) ; }
};
======================================

The error message reads:
  bug.cc: In member function 'void A::bar()':
  bug.cc:4: error: could not convert '#'obj_type_ref' not supported by
dump_expr#<expression error>(this)' to 'bool'

With GCC 3.4.4 I get
  bug.cc: In member function `void A::bar()':
  bug.cc:4: error: could not convert `(**((A*)this)->A::_vptr.A)(((A*)this))' to
`bool'
which is better, but not optimal.
