C++11 ABI Compatibility for 4.8 and 4.9?

C++11 ABI Compatibility for 4.8 and 4.9?

[Lars Hagström]

Hi,

I've been trying to read up on the ABI compatibility between C++11 and
C++03/98, and one of the pages that I've read is
http://gcc.gnu.org/wiki/Cxx11AbiCompatibility
This wiki page addresses GCC 4.7.

I've read a comment on stackoverflow
(http://stackoverflow.com/questions/13383124/g-std-c0x-and-compatibility)
by Jonathan Wakely that some of these issues would change or be
resolved in 4.8.

Elsewhere I've read that 4.8 would introduce more breakages compared to 4.7.

What is the status of these issues in 4.8 and 4.9? Is there any chance
of someone in the know updating the wiki?

Cheers
Lars

It's still relevant for 4.8 and 4.9

Apart from the items noted as only affecting 4.7.0 and 4.7.1,
everything there still applies.

And no new issues have been introduced?

Not that I can think of right now.
