Segfault with mawk

[Sander Kleywegt]

release: ubuntu 12.04.1 LTS
mawk version: 1.3.3-17
Got a segfault with: echo "x" | awk "/x/ { print \"(`cat test`)\"; next; } { print; }" -

'test' file attached

removing a few chars from the test files resolves the issue

[Thomas Dickey (dickey-his)]

I can reproduce that (with the Ubuntu package).
my version does not show this defect.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Benno Fünfstück (benno-fuenfstueck)]

Also affects me, Ubuntu 12.10. same mawk version.

mawk in Ubuntu and Debian is 18 years, see LP bug #1332114
I think this bug should be marked as duplicate of bug #1332114
Many bugs of Mawk are fixed in a new upstream versions 1.3.4-2010nnnn-2015nnnn, but the Debian maintainer does not want to update for an obscure reason.
We need to push here: http://bugs.debian.org/554167

apport information

[Alberto Salvia Novella (es20490446e)]

Because mawk is not POSIX compliant, cannot be updated safely without great risk of breaking things.

[Thomas Dickey (dickey-his)]

Actually, a specific example would be useful and constructive information.
Your comment is neither.
