Ok, I got that new commit of you.  But, it still cores
in the same place :/

I also tried it without flags (just the default flags), with the
same result.  Hence it is not the result of using -O9 or whatever
that I do special.

I also tried replacing memset with bzero and indeed then it passes
that line to core in another place, also a memset(start, 0, sizeof).
I replaced three memsets with bzero until it cored in a place where
there is no memset - then I gave up.
