>Description:
When rethrowing an exception from within an exception handler, a segfault occurs.
>How-To-Repeat:
#include <iostream>
#include <stdexcept>
//
// Extended bad_exception class with info on exception no handled in the
// throw specifier
//
class unhandled: public std::bad_exception
{
public:
unhandled( const std::string& what )
: m_what( what )
{
}
~unhandled() throw() {}
virtual const char*
what() const throw()
{
return m_what.c_str();
}
private:
std::string m_what;
};
//
// New handler for unexpected exceptions
//
void
handle_unexpected( void )
{
try {
throw;
}
catch( std::bad_alloc )
{
throw unhandled( "bad_alloc" );
}
}
//
// No problem
//
void
c1( void ) throw ( std::bad_alloc )
{
throw std::bad_alloc();
}
//
// No problem
//
void
c2( void )
{
throw std::bad_alloc();
}
//
// Problem do to bad_alloc not being in throw specification
//
void
c3( void ) throw ( std::bad_exception )
{
throw std::bad_alloc();
}
main()
{
std::set_unexpected( handle_unexpected );
try {
c1();
}
catch ( const std::bad_alloc& e )
{
std::cerr << "Caught exception for c1" << std::endl;
}
try {
c2();
}
catch ( const std::bad_alloc& e )
{
std::cerr << "Caught exception for c2" << std::endl;
}
try {
c3();
}
catch ( const std::bad_alloc& e )
{
std::cerr << "Caught exception for c3" << std::endl;
}
catch ( const std::bad_exception& e )
{
std::cerr << "Caught bad_exception for c3" << e.what() << std::endl;
}
}
