[Debian-med-packaging] Bug#716373: Tried hard to fix reason for crashed but failed

[Andreas Tille]

Hi Cedric,

in the bug log of Debian bug 716373[1] you wrote that you are interested
in this kind of reports.  I tried hard to fix similar issues of other
packages that were inspected by Mayhem but I admit I failed in a sensible
time frame in the t-coffee case.  I can confirm that I found a way to
reduce the chance for infinite loops by this patch[2] but the segmentation
fault which is probably caused by some pointer boundaries before remains.

You can reproduce this by the test case provided by the bug reporter[3].
If you unpack the archive there is a script t_coffee-report/crash/crash.sh
which ends up in a segmentation fault when exiting.

However, I was able to fix Debian Bug #751579 and with the patch[4]
~/.t_coffee/ is not world-writable any more.  May be you can include this
in your next release.

I have also closed Debian Bug #631249[5] since according to the build
logs of different architectures[6] t-coffee builds fine on armel where
the problem was reported.  If users on this architecture might notice
some problem it is easy to reopen this bug.  BTW, it would be great if
you could provide some test suite we could run at build time to see
whether t-coffee works as expected.

Kind regards and thanks for providing t-coffee as Free Softwar

        Andreas.
