It will lead to the lsb test caes
/libstdcxx-t2c/tests/LanguageSupport/LanguageSupport FAIL.
So I want to know the right return value of std::uncaught_exception() (inside
exception-constructor).
The LSB test code is as follows:
cat main.cpp
#include <string.h>
#include <iostream>
using namespace std;
class exception_test : public exception
{
public:
bool result;
exception_test(): exception(){result = uncaught_exception();}
~exception_test() throw(){};
};
int main(int argc, char ** argv)
{
bool result;
try
{
throw exception_test();
}
catch(exception_test et)
{
result = et.result;
}
cerr << result << endl;
return 0;
}
# g++ ./main.cpp
# ./a.out
0
My GCC version is 4.9.2, the return value of result is 0,and the test is FAIL.
If the the return value of result is 1,and the test will be PASS.
