Hi Matthew,
Thanks for the report, and sorry to hear you have trouble with your
valuable project.
I have no objection with rebuilding everything with FORTIFY_SOURCE=0,
but it seems it would be the bug you triggered is fairly rare, and it
would be nice to:
- have a minimal patch or set of patches to reproduce, preferably one
not using externals
- make sure you can not reproduce it when rebuilding without fortify
Thanks, Paul

Package: puredata Version: 0.43.2-4 Severity: grave
I have a large puerdata patch using GEM that was working early on
last year.
At the moment it is crashing on start with calls to __fortify_fail()
in libc.
There are two pds running, one handling sound and wiimote input, and
a slave doing GEM display work. They communicate over a TCP socket.
Pure data with the _FORTIFY_SOURCE=2 is not usable for any serious
work, destroying the purpose of the porting and packaing to Debian
The same problems also show up in puredata plugins/libraries with
this turned on as well. The one that blew up in the same way was
gem-plugin-magick
I know that this is security hardening, and that buffer overflows
are bad in any application, as they tend to go and corrupt the
running application.
But puredata is an interpreted langauge progam used by artists
typically on closed off networks behind a firewall/router. It is
hard enough to get going properly with out this unneeded security
stuff being turned on. Please compile pruedata with _FORTIFY_SOURCE=0
for the whole puredata module stack and dependencies until the causes
of this are fixed upstream.
I am going to try the puredata package compiled with
_FORTIFY_SOURCE=0, and see if I can get my valuable project going
again.
BTW, I am a Debian Developer.
Cheers,
Matthew Grant
