You must not be living right.  I have this:

g++ --version
powerpc-apple-darwin8-g++-4.0.0 (GCC) 4.0.0 20041026 (Apple Computer, Inc. build 4061)

uname -a
Darwin taz.sci.utah.edu 8.1.0 Darwin Kernel Version 8.1.0: Tue May 10 18:16:08 PDT 2005; root:xnu-792.1.5.obj~4/RELEASE_PPC Power Macintosh powerpc

I just checked out a fresh copy, set the build mode to Release, and it worked fine.

Note that you get a significant performance improvement by adding -malign-natural to the set of command line flags. However, it doesn't work on the old gcc, so we didn't make it the default.

Andrew, or someone else with a Mac - can you check the same thing?

I'm trying to get manta working on a G5 Mac here.  I've built the main trunk with a RELEASE build type that causes a whole lot of compiler flags to get used.  The resulting binary has some issues, as illustrated by the attached image.  When I compile with only "-O3"  the image looks fine.  Anyone seen this before?
 
"g++ -- version" reports powerpc-apple-darwin8-g++-4.0.0 (GCC) 4.0.0 20041026 (Apple Computer, Inc. build 4061).
