Bug ID: 57632
Summary: Operator new overloads with stdc++11 enabled looses
exception specifier (MacOsX)
Product: gcc
Version: 4.8.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: b...@odd-e.com
G++ on MacOsX acts different when enabling the new c++11 related to operator
new overloads. If I compile the following code:
#include "stdlib.h"
#include <new>
void* operator new(size_t mem) throw(std::bad_alloc);
void* operator new(size_t mem) throw(std::bad_alloc);
Then when compiling g++ new.cpp, it compiles fine.
But when I compile g++ -std=c++11 new.cpp, then it results in this error:
new.cpp:6:52: error: declaration of ‘void* operator new(size_t) throw
(std::bad_alloc)’ has a different exception specifier
void* operator new(size_t mem) throw(std::bad_alloc);
^
new.cpp:5:7: error: from previous declaration ‘void* operator new(std::size_t)’
void* operator new(size_t mem) throw(std::bad_alloc);
^
------------
I've not been able to replicate this under linux and digging into it a bit, it
seems to relate to the c++config.h definitions of _GLIBCXX_THROW.
