That part is in the text that follows what you quoted above, and was
kind of the point (cf. gcc46 in the subject of the message).

The failures in testing bsxfun.cc that David reported in his initial
message, and that I reported elsewhere in this thread, are for builds
using gcc-4.6.2 from Fink.

It's worth pointing out that on my OS X 10.5 builds (all
architectures) Apple's gcc-4.2 compiler does _not_ produce this issue.
