Bug ID: 57505
Summary: [C++11] destructor of std::function should be noexcept
Product: gcc
Version: 4.7.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: f.heckenbach@fh-soft.de

Test case
According to
http://en.cppreference.com/w/cpp/utility/functional/function/~function, the
destructor of std::function, like all standard destructors, should be noexcept,
but as the attached test case shows, it isn't so:
% g++-4.7 -std=c++11 test.cpp
test.cpp:4:1: error: static assertion failed: ~function is not noexcept

Test case for enable_shared_from_this
The same applies to std::enable_shared_from_this.

This is fixed in gcc 4.9 trunk and I believe it has already been fixed in gcc
4.8 due to bug #50043.

cecky2.c: More test case
(In reply to Andrew Pinski from comment #3)
> I thought this was fixed for 4.8 by bug 54295.
My 4.8 is dated some days before the release candidate, around 2013-03-06. If
I understand correctly, that 4.8.0 (experimental) contains the fix for PR54295
but still generates wrong code?
And I don't see a backport to 4.7.
Thus the fix for PR54295 is not complete, or this is an other, unrelated
problem.
