[racket-dev] Can't Find a Workaround for Bug 11017 in DrRacket

Sam appears to be corrects.

If "No Debugging or profiling" is selected, I get the backtrace. If
"Debugging" is selected, I only get the error message. And, most
interestingly, if "Debugging and profiling" is selected, it runs correctly.

Also, Robby's suspicion that it would run correctly if "Populate compiled/
directories (for faster loading)" is unchecked, seems to be true. It does
run when it is unchecked.
