[pkg-apparmor] Bug#799449: apparmor: FTBFS: test suite segfaults on mips and mipsel

[intrigeri at debian.org]

Source: apparmor
Version: 2.10-2
Severity: important

https://buildd.debian.org/status/fetch.php?pkg=apparmor&arch=mips&ver=2.10-2&stamp=1442250379
https://buildd.debian.org/status/fetch.php?pkg=apparmor&arch=mipsel&ver=2.10-2&stamp=1442250826

I've reproduced these segfaults on the minkus.debian.org (mips) and
eder.debian.org (mipsel) porterboxes.

Note that:

 * 2.10-1 built just fine on those architectures' buildds when that
   package was uploaded to experimental.
 * I tried building 2.9.2-3 on these two porterboxes => I see the same
   segfault and FTBFS, and running ./parser/tst_regex by hand indeed
   tells me: "zsh: segmentation fault  ./parser/tst_regex"

=> so this looks like the breakage was triggered by some change in the
build environment, rather than in the source package itself. (Which
doesn't necessarily mean that the source package is innocent,
though :)

Could it be that there's some inconsistency between the version of
libapparmor we're building/linking the test programs against, and the
version we're running them with? The system's libapparmor1 (2.9.2-3),
has been built before the GCC-5 transition.

Cheers,
