GCC-10 build fail on riscv64 (breaks test)

[Christian Ehrhardt ]

Since GCC_10 is in Ubuntu we see a build fail (or actually a build-time-test fail).

It looks like this:
30/52 Test #29: test_ContactConstraint ............***Exception: SegFault 4.34 sec
Running main() from /<<PKGBUILDDIR>>/unittests/gtest/src/gtest_main.cc
[==========] Running 1 test from 1 test case.
[----------] Global test environment set-up.
[----------] 1 test from ContactConstraint
[ RUN ] ContactConstraint.ContactWithKinematicJoint

I reported it upstream at
https://github.com/dartsim/dart/issues/1482

And to Debian at:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=968332

I'm still trying to re-create the same in a riscv64 qemu guest, but so far had no luck (last time I hit an OOM before the tests).

Right now I'm considering skipping this particular test in Ubuntu for the time being.
That would unblock the package, if working I can suggest the same to Debian as well.

First with a 2GB guest the build OOMed at some point.
Now after 8h of build still only at 87% through the build :-/

Gladly at least a successful build at [1] shows that a skip of that particular test on riscv64 will work

I'll give the build the night to complete for a try at fixing the underlying issue.
But otherwise I'll upload the test skip tomorrow.

I debugged this for quite a while and helped the upstream project to know where things are.
But there is no fix out of that, therefore a test (juts this case) skip it will be for groovy.

This looks to me almost more like a gcc-10 bug breaking the function returns in some way, see [1] for more. For the sake of completeness I'll add a gcc-10 task here.

Fix uploaded to groovy (as it test built in my PPA before).

[Launchpad Janitor (janitor)]

This bug was fixed in the package dart - 6.9.2-3ubuntu1

---------------
dart (6.9.2-3ubuntu1) groovy; urgency=medium

  * d/rules: GCC-10 issue on riscv64, skip the one failing test for now
