[Message part 1 (text/plain, inline)]

I installed the attached patch into master, to work around the 
getloadavg-related assertion failure. However, I don't think this fixes the 
actual bug.

If so, you should be able to step through the replacement getloadavg and see why 
it's reporting bogus values. I have the sneaking suspicion that floating point 
isn't working properly, and that it's treating tiny numbers as NaNs or vice 
versa. But this bug is relatively unimportant.

The main problem here seems to be the sigsetjmp-related bug. You might try 
putting a breakpoint on handle_sigsegv before running Emacs; that might give you 
a better backtrace.
