Bug ID: 61643
Summary: [C++11] std::uncaught_exception returns wrong values
after std::rethrow_if_nested
Product: gcc
Version: 4.10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: ai.azuma at gmail dot com
The following program should terminate successfully.
//=========================================================
#include <stdexcept>
#include <exception>
#include <cstdlib>
struct X
{
~X() {
if (!std::uncaught_exception()) std::abort(); // (A)
}
};
int main() {
try {
throw std::runtime_error("");
}
catch (...) {
try {
std::throw_with_nested(std::runtime_error(""));
}
catch (std::runtime_error const &e) {
try {
X x;
std::rethrow_if_nested(e);
}
catch (std::runtime_error const &e) {
if (std::uncaught_exception()) std::abort(); // (B)
}
}
}
return EXIT_SUCCESS;
}
//=========================================================
However, the program is aborted at the line marked with `(A)', and at the line
marked with `(B)' if the line marked with `(A)' is commented out.
This problem is reproduced with 4.10.0 20140622, 4.9.1 20140625 and 4.8.4
20140619. The reproducer requires -std=c++11 flag to compile.
