I am almost certain that it does not.

Back around 2.0B5 or so, I installed the Mr. Bus Error INIT, which
repeatedly stomps location 0 with an odd doubleword... this rapidly
detects code which is dereferencing an empty-but-not-null handle (very
much a no-no).  Boomerang immediately began suffering from bus errors,
aborting the current application.

I dumped the code-segment in question, printed it, marked it up, and
mailed it off to Hiro.  A couple of weeks later, a new beta-version appeared
on the various nets, with this problem corrected.  Shortly thereafter,
I got a diskette from Hiro, with the fix installed and a note of thanks
for reporting the bug.

If this is the same problem you observed (I suspect it is...), then the
problem should be absent from the release version and from the later
beta-versions (2.0B9, for example).  I'm running 2.0 on my SE at work,
with Mr. Bus Error, and am running 2.0 at home with occasional use of
NilMinder.  I've seen _no_ bombs, Boomerang wipeouts, or other impolite
behavior.
