Bug ID: 61966
Summary: [C++11] std::terminate called after throwing exception
from destructor [g++] [4.8.2] [4.9.1]
Product: gcc
Version: 4.8.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++

ii file - 4.8.2
According to C++ standard 15.2.2 - It's allowed to throw exception from class
destructor. If exception from destructor thrown during stack unwinding
std::terminate is called, otherwise exception should be handled normally
Problem exists only with -std=c++11, version 4.6.0 behaves ok
Here is code which generates call to std::terminate though standard allows it:
class Exc : public std::exception {
public:
virtual const char* what() const throw()
{ return "test exception"; }
};
class Test {
public:
Test()
{ }
~Test()
{
throw Exc();
}
};
int main()
{
try {
{
Test();
}
}
catch (Exc& exc)
{
std::cout << exc.what() << std::endl;
}
}
Compile line:
g++ -v -save-temps -Wall -Wextra -std=c++11 exc-terminate.cc
-------------------------------- g++ 4.8.2 output ---------------
Using built-in specs.
