I've looked more closely into this one. Something goes bad when d2f 
bytecode instruction is exectued in this case. the implementation in 
intrp/icode.h looks innocent enough, but I'm not sure what should happen 
precisely when max double is assigned to a float in C. I've written a 
test case, and attached it, so it'd be nice if you could run it on your 
netbsd-ppc machine and report the results.

cheers,
