Package: bash
Version: 3.1-1
Severity: normal
The following command segfaults at line 4097:
% seq 0 10000 | while read line; do /bin/echo $line ; done | tail -2
4095
4096
The seq, echo and tail commands are for illustration only, they are
not related to the bug. I originally discovered the bug with completely
different commands, but the above is the simplest illustration of the bug.
The segfault appears when the input reaches line 4097, and when an
external command is invoked.
If you use the builtin echo, the bug doesn't appear:
% seq 0 10000 | while read line; do echo $line ; done | tail -2
