In src/mesa/dri/drivers/r300/compiler/r3xx_fragprog.c around line 120, there is
a list of compiler passes.  Three of these passes(deadcode, dataflow optimize,
and register allocation) are disabled when running with RADEON_DEBUG=noopt. 
You could try commenting out these passes one a time to see which one is
causing the bug.  When you are testing this way _don't_ use RADEON_DEBUG=noopt
