Obscure crash on hash -d

Hello,

by accident, I just stumbled over this:

% uname -a
Linux zorya 2.6.32-ARCH #1 SMP PREEMPT Tue Feb 23 19:43:46 CET 2010 x86_64 Genuine Intel(R) CPU U4100 @ 1.30GHz GenuineIntel GNU/Linux

% echo $ZSH_VERSION $ZSH_PATCHLEVEL
4.3.10 1.4705

% hash -d ~=x
hash: invalid character in directory name: ~
zsh: segmentation fault  zsh

(gdb) bt
#0  0x000000000041189b in ?? ()

(I tried to see if I could define ~~ to mean something.)

Thanks for your great shell,
