[sldev] XCode bug - please help figure out why

[Michael Miller]

Apparently, I spoke too soon. Removing those lines does NOT fix the problem.
I changed the source a bit, and rebuilt it, and the binary does not
run(technically it does, but it quits after eating up a lot of CPU with a
"segmentation fault"). Thus, the problem lies not(at least completely) in
those few lines being mangled. Any other suggestions?
