threading problems - arithmetic error - revno 1174

[John Hein]

I made a virtual folder (using V S) of four messages

On the first C-t, I got:

vm-build-threads: Arithmetic error

On the second:

Generating summary... 0

On the third, it pegged the CPU for maybe 20 seconds and again:

Generating summary... 0

And the virtual folder was still sorted by 'physical-order'.

Exiting the virt folder and turning on debug-on-error gives:

Debugger entered--Lisp error: (arith-error)
  vm-build-reference-threads(([[#<marker at 1 in (INBOX.curr subject Creating Archives)> #<marker at 34 in (INBOX.curr subject Creating Archives)> #<marker $
  vm-build-threads(nil)
  vm-sort-messages("activity")
  vm-toggle-threads-display()
  call-interactively(vm-toggle-threads-display nil nil)

For another (single message) virt folder ...

Debugger entered--Lisp error: (arith-error)
  vm-build-reference-threads(([[#<marker at 1 in (INBOX.curr subject Opening Day Scrimmage rules)> #<marker at 34 in (INBOX.curr subject Opening Day Scrimma$
  vm-build-threads(nil)
  vm-sort-messages("activity")
  vm-toggle-threads-display()
  call-interactively(vm-toggle-threads-display nil nil)
  recursive-edit()
  byte-code("\306^P @\307=\203!^@\310\311\312\"\210\313\311!\211^ZA@)\242\314=\203!^@\310\315\312\"\210\316^K!\210\317 \210\320 !\210\f\203d^@\321ed\"^MV\20$
  debug(error (arith-error))
  vm-build-reference-threads(([[#<marker in no buffer> #<marker in no buffer> #<marker in no buffer> #<marker in no buffer> #<marker in no buffer> #<marker $
  vm-build-threads(nil)
  vm-sort-messages("activity")
  vm-toggle-threads-display()
  call-interactively(vm-toggle-threads-display nil nil)

Yeah, sorry, there is indeed an arithmetic error in revision 1174,
which got fixed in 1175.

You can also use the latest revision, 1181, which seems to be working
ok.

Cheers,
Uday

I'm now using 1181 and the reported problem is gone.
