Package: libstdc++6-4.2-dev
Version: 4.2.2-5
Severity: important
This revision includes r130944 of branches/gcc-4_2-branch which, among other
things, changes use_facet in libstdc++-v3/include/bits/locale_facets.tcc to use
dynamic_cast.
This breaks programs that use <iostream> and compile with -fno-rtti
and -finline-functions (e.g. see #459031)
Here is a simple program that demonstrates the problem:
#include <iostream>
int main(void)
{
std::cout << 42;
return 0;
}
This compiles ok with 4.2.2-4 but fails with 4.2.2-5:
