* [Bug c++/33492] New: [4.1/4.2/4.3 regression] Broken diagnostic: 'must_not_throw_expr' not supported by dump_expr

The C++ frontend generates a broken diagnostic for the following code
snippet since GCC 3.4.0:
=======================
void foo()
{
if (throw 0)
;
}
=======================
bug.cc: In function 'void foo()':
bug.cc:3: error: could not convert 'throw((__cxa_allocate_exception(4u),
#'must_not_throw_expr' not supported by dump_expr#<expression error>),
__cxa_throw(<anonymous>, ((void*)(& _ZTIi)), 0u))' to 'bool'
The "'must_not_throw_expr' not supported by dump_expr" is not implemented,
and the rest of the error message isn't very helpful either.

Sorry, that's actually since GCC 3.0.

------- Comment #2 from mmitchel at gcc dot gnu dot org 2007-09-28 04:09 -------
This kind of problem is why I have long said that we should never, ever try to
dump expressions. Because we lower some expressions up front, we cannot
possibly reconstruct good expressions from TREE. Instead, we should do what
EDG does: give accurate source positions (file, line, column) for the offending
expression.

Hi Gaby. Any suggestions for this bug? The must_not_throw_expr thing is trivial
(just like non_dependent_expr, cxx-pretty-print.c is already ok), but what
about the rest, short term? Thanks.
