Thanks for your report!  I've fixed this for man-db 2.6.0:

Thu Apr  7 12:46:34 BST 2011  Colin Watson  <cjwatson at debian.org>

        * lib/cleanup.c (do_cleanups): Set tos and nslots to 0 before
          freeing stack, in case do_cleanups_sigsafe is called again from a
          signal handler (Fedora bug #694332).
        * NEWS: Document this.
