The problem is with current Debian unstable:

$ gcc --version | head -1
gcc (GCC) 4.2.3 20080102 (prerelease) (Debian 4.2.2-5)

I'm seeing mysterious testsuite failures when the entire binary is
compiled with -O2, and fewer, different mysterious testsuite failures
when the entire binary is compiled with -O1.  See
http://buildd.debian.org/fetch.cgi?pkg=monotone;ver=0.38-1;arch=alpha;stamp=1197984342
(that's -O1; alas, all previous failing build logs (at -O2) seem to
have expired off the page).

It may be that it's all botan's fault, but I don't immediately see how
botan could break the cset_invalid_csets unit test.

I'm inclined to blame the compiler because (a) this happens
exclusively on alpha, and (b) the failures are in test cases for logic
that hasn't changed in ages.
