601974 - [clang]: error: exception specification in declaration does not match previous declaration MOZALLOC_THROW_BAD_ALLOC in /toolkit/xre

Status: RESOLVED FIXED

(Core :: XPCOM, defect)

Description

[Nomis101]

Attachment: Buildlog with errors

Building with Clang on Mac OS X 10.6 gives a lot of errors like:

../../dist/include/mozilla/mozalloc.h:224:7: error: exception specification in
      declaration does not match previous declaration
void* operator new(size_t size) MOZALLOC_THROW_BAD_ALLOC
      ^

for /mozilla/toolkit/xre. Because the error is a bit long, I've attached it as a text file. As I remember there was a similar error for Bug 576355.

keep -fexceptions and MOZ_CPP_EXCEPTIONS in sync

Let's just centralize the logic and set ENABLE_CXX_EXCEPTIONS = 1 here.
