exception and global variable

[George2]

Hello everyone,


Bjarne mentioned in his book, that there is no way to catch exceptions from the initialization of global variables (section 14.7). But I do not think it is true, because we can add function try block to its constructor, and catch appropriate types of exceptions or using catch(...) to catch all exceptions.

Am I correct? Any comments?


thanks in advance,
George

Why not post some code that would serve as a counterexample to Stroustrup's statement?

Hi laserlight,


Here is the code to verify exception from constructor of global variable could be caught. Anything wrong?

#include <iostream>

using namespace std;

class Foo{

public:

	Foo ();
};

Foo::Foo()
try{
	cout << "constructing" << endl;

	throw(0);

} catch (...)
{
	cout << "catch exception in constructor" << endl;
}


Foo foo;

int main()
{
	int i = 0;

	cout << i;

	return 0;
}

Why not post some code that would serve as a counterexample to Stroustrup's statement?

regards,
George
