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.
