Package: tcsh
Version: 6.17.02-4
Severity: normal
tcsh(1) segfaults when prompt includes %j and there are more than 10 jobs.
Example:
> set prompt="%M %j %#"
> sleep 90s & [repeated 10 times]
On the 10th invocation, tcsh segfaults, as shown by dmesg:
[329726.521173] tcsh[26771]: segfault at 7fff0e0df000 ip 000000000043f58a sp
00007fff0e0dd930 error 6 in tcsh[400000+58000]
The segfault can also be provoked by setting the prompt variable to include %j
when there are already 10 or more jobs.
Problem also occurs on tcsh 6.17.00 (Astron) 2009-07-10 (x86_64-unknown-linux)
(tested on Ubuntu 10.10).
