man-db: crashes and possible fix

[Yaakov Selkowitz]

WRT mandb -c crashing or aborting:

* I can reproduce this on x86_64, but not on x86.

* I can reproduce that mandb -cd doesn't crash but it doesn't complete 
successfully either; the difference being if there is a 
/var/cache/man/index.db or just a numbered file there (the PID, 
specifically).  So that is not really a solution.

* On x86_64, increasing the stack commit size seems to help:

peflags -X0x20000 /usr/bin/mandb.exe

(Note that is a capital X.)

* Even with that, it still takes over 20 minutes to complete.

Has anyone found differently, and does the peflags command above help?
