<pre style="margin-left: 2em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I get a compile warning (gcc 4.4) on this line. "'n_buckets' may be used uninitialized in this function"
Personally, I don't see it. All possible values for test_container_type are handled in the switch statement, and each of those is guaranteed to set n_buckets to something.
I thought it was weird I was seeing it here but not in trunk. Turns out I was never compiling this file in trunk when I'd test-compile things. Sure enough, I get the same warning there, too.
So, while I think the compiler is full of it, you'll need to do something to get rid of the warning. I got around it by adding a default case to the switch and returning a test failure.</pre>
