dynamic_cast of ostream

[Peter Kelb <peter dot kelb at mchp dot siemens dot de>]

Hi folks,

the following program produces a segmentation fault

#include <iostream>

class A : public std::ostream {
public:

 A() : std::ostream(std::cout.rdbuf()) {}
};

A* test(std::ostream* os) {
 return dynamic_cast<A*>(os);
}

int main(int argc,char* argv[]) {
 std::cerr << (dynamic_cast<A*>(&std::cerr) == 0) << "\n";
 std::cerr << (test(&std::cerr) == 0) << "\n";
}
 

compiler: g++ 2.95.2
os: Linux Suse 6.3 on PIII 450 MHz

Regards, Peter Kelb
