Comment:

 As it happens, I see the same problem with the log4cxx port that we do
 have. It happens on our Snow Leopard buildbot only, not on the newer
 buildbots. The Snow Leopard buildbot is the only one that uses gcc-4.2 as
 its default compiler, and I'm able to reproduce the problem on Mavericks
 if I use `configure.compiler=apple-gcc-4.2` so it's some problem with old
 GCC. After some trial and error, I found that switching the optimization
 flags from `-Os` (the default as of MacPorts 2.2) back to `-O2` (the
 default in previous versions of MacPorts) fixes it, so that seems the
 simplest fix.
