zsh-4.3.1[45] problem on FreeBSD

["Herbert J. Skuhra" <hskuhra@xxxxxxxxxxx>]

Hi,

after upgrading zsh from version 4.3.12 to 4.3.14 (and later 4.3.15) I
have a strange problem on FreeBSD 9.0-PRELEASE (i386).

When I launch xterm/sakura/urxvt instead of the shell prompt I only see
the cursor.

96450 herbert       1  89    0 11452K  2888K RUN      0:49 59.96% zsh
96448 herbert       1  52    0 14372K  5944K select   0:35 40.97% xterm

Ktrace shows an endless loop of:
