Re: [Nel] dynamic_cast pbs...

[Lionel Berenguier]

There is maybe a configuration problem with dynamic_cast in gcc. If someone
(good in gcc) could check options, to see if RTTI is enabled, it would be
helpfull.

We have no problems here with dynamic_cast under Visual. It may be a
solution to check GCC compiler in safe_cast() and avoid the nlassert, but we
really use dynamic_cast() at other place in the code (ie not for check).
