For what it's worth, there is a recognition of the issue of running regression
tests under debug only (search the mail archive if you really want to read
about it). And, in fact, we do now have some platforms running tests using
release configurations where inlining should be enabled. I believe the 1.33
is the first Boost release to have achieved this level of testing -- so, in
fact, I believe the level of Boost testing has never been higher.

What I'd learn is that Boost is getting ever bigger in size and more popular.
 So even if we are getting better at testing we might very well see 'more
bugs' after a release because there's more code to have bugs and more people
with more configurations to see them. This dynamic is likely to continue.

I agree.
