Note also that the bug is specific to zsh. Other shells work fine:
$ dash -c 'echo `seq 1 1234567` | wc'
1 1234567 8765432
$ ksh93 -c 'echo `seq 1 1234567` | wc'
1 1234567 8765432
$ mksh -c 'echo `seq 1 1234567` | wc'
1 1234567 8765432
$ bash -c 'echo `seq 1 1234567` | wc'
1 1234567 8765432
$ posh -c 'echo `seq 1 1234567` | wc'
1 1234567 8765432
while with zsh:
$ zsh -c 'echo `seq 1 1234567` | wc'
0 0 0
Removing the "| wc" shows that this is due to a segmentation fault.
I've reported the bug on the Debian BTS:
