It might be one of these things that prevent data execution.  With the
jit on, Racket is basically throwing some numbers into memory and then
executes them -- which is a power that some people don't like.  It
(Racket) does do the right thing an marks those memory pages as
executable, but it looks like something on your system is preventing
it somehow, possibly leading to that block.
