I'm using valgrind today and am seeing a lot of these errors/warnings

Checked into mapfile.c and it looks like the gt members of projections are not
being initialized in msInitProjection.

Sean,

I have committed some initialization code in msInitProjection().  I don't know
how I missed this back when doing the geotransform stuff.  Kind of scary!

Let me know if you still see problems.

Thanks, Frank.  I mighta tried to fix this myself but I don't know my way
around the geotransform stuff at all.  All the warnings about conditional
jumps are gone from the single test I am running.
