Comment 1 for bug 2051421

And here are the results (for reference, low single digits failures are what I'd consider normal).

So far I've only looked at a few. The 'none' tests are all related to the build failures.

The leak ones are likely to be semi-spurious - it's hard to make leak detection very robust as memcheck will search memory (and registers) for pointers to unfreed memory. That can cause mis-categorization from the view of the testcase.

The varinfo ones look like problems with DWARF debuginfo.

getaddrinfo, I might need to add that to the suppressions. Debugging with /usr/lib/arm-linux-gnueabihf/libnss_mdns4_minimal.so.2 debuginfo would help.
