My problem is with stable-0.12.  Consider upstream fixed.

1) Bug reported against qemu-0.12.0.
2) Developer writes patch against master, submits, all is well except for the CODING_STYLE argument it triggers. 3) Developer writes patch against stable-0.12, can't test because testing crashes in some place where production doesn't crash.

Stable-0.12 always carries a VERSION of 0.12.x where x < 50. This means that the stable-0.12 branch will always behave like a production release.

You don't get -Werror on stable-0.XX and you won't get zero malloc()s assert.


That's good enough for me. Allow 0 for 0.12 and new allocation functions for mainline, then?
