Yes, please do submit bug reports to Apple if you think it is an Apple
problem.
But some of the problems are clearly GCC bugs. For example, all the ublas
tests are failing with this message:
...error: due to a defect in the G++ 3.2 ABI, G++ has assigned the same
mangled name to two different types...
This is happening on Apple, Linux, and Windows, so that bug report should
go to GCC.
GCC 3.3 (and 3.2.x, too, I think) also has some pretty bad behavior as far
as memory usage goes. It uses 2.5 gigabytes on random_test (on both Win 2K
and XP) before dying. It also outputs weird error messages about heap
problems if you run bjam with the -j2 option (which tries to execute the
build and test as multiple processes.) Too bad, because -j2 speeds bjam
runs up at least 20% on my P4 with hyperthreading.
So by all means, do submit bug reports.
Thanks,
