[Bug c++/13944] [3.3/3.4/3.5 Regression] exception in constructor of a class to be thrown is not caught
--- Additional Comments From jason at redhat dot com 2004-02-16 18:22 --- Subject: Re: [3.3/3.4/3.5] exception in constructor of a class to be thrown is not caught EDG performs this same optimization, but they seem to have made a different choice as to whether or not the call which creates the object should be allowed to throw; it seems impossible to construct a testcase which will terminate due to a throw during the initialization of the exception object. Their choice, which the submitter of this bug also expects, seems reasonable to me.

Subject: Re: [3.3/3.4/3.5] exception in constructor of a
class to be thrown is not caught
Actually, this testcase does terminate under EDG:
struct A
{
A() { }
A(const A&) { throw 1; }
};
int main()
{
A a;
try
{
throw a;
}
catch(...)
{
}
}
To match this behavior, we need to treat cases where we elide the copy
constructor differently, as discussed in my comment in build_throw.

Here's the backport; I'm testing it now.
