Bug#188943: g++-3.2: code using dynamic_cast causes segfaults when -fno-rtti is used

[Sean Perry <shalehperry@attbi.com>]

Package: g++-3.2
Version: 1:3.2.3-0pre7
Severity: normal

Now obviously, dynamic_cast requires rtti so using -fno-rtti is silly.
I ran into this on a C++ project where we had been using -fno-rtti because rtti
was not used.  A recent commit added dynamic_cast code and started segfaulting.
It was believed that the dynamic_cast was at fault and this caused some finger
pointing.  Then the no-rtti was noticed.

The compiler should give a warning (or perhaps even an error) if code requiring
rtti is used while the -fno-rtti option is in effect.
