Subject: xload dumps core with new phkmalloc
From: asami@cs.berkeley.edu (Satoshi Asami)

Hello.  I found that xload dumps core with "floating point exception"
with the latest phkmalloc (supped yesterday).  "MALLOC_OPTIONS=Z" will
fix it, so it's definitely xload's problem.

I changed the only "malloc" in the xload source to "calloc" but that
didn't help, so I guess the bug is in a more fundamental level.  This
is what gdb has to say:
