Revision 1fda3d557b7c9e19e008c3a3d77f1922341796d7 authored by Mark Wooding on 03 February 2006, 20:27:02 UTC, committed by Junio C Hamano on 04 February 2006, 07:33:20 UTC
Could cause a crash if --base-path set.  Unlikely to be a security the
concern: message doesn't go to the client, so we can't leak anything
(except by dumping core), and we've already forked, so it's not a denial
of service.
