[...] No, and sorry if my first reply grumbling about how old GCC 4.4 is sounded that way! We have to live with compiler bugs no matter how old the compiler is, the release cycles are decoupled to such a degree and external tooling propagates with such high latencies that that's the only sane thing to do. We also officially support GCC 3.2 and later compilers. Had this regression not been resolved within a week or so I was fully ready to queue up a revert commit, no questions asked. Plus it's not just that it's a regression, but adding support for a different compiler is about the _worst_ possible reason to break working compilers ... > [...] People who then step up and analyze the problem are rare as it is.

I'll lower the threshold for adding such tags, to create further incentives for people to help debug crashes. Thanks, Ingo
