This is happening intermittently but regularly. The command being run is....
docker run --rm \
-v "$ABS_CURDIR:/build" \
--workdir /build \
sh -c "nuget restore && xbuild /p:Configuration=Release"
As you can see we are running mono in a docker container so I'm not absolutely certain that it's mono and not docker causing the problem, but I suspect mono is more likely. It looks like it's the nuget restore stage that is failing.
and the log shows this...

Debug info from gdb:
Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.
I should add that we run exactly the same command on our MacBooks (OS X Yosemite 10.10.4) and this has never happened. It only ever happens running on out Linux build server
On that server:
Ubuntu 14.04.2 LTS \n \l
Linux ip-10-100-52-164 3.13.0-49-generic #81-Ubuntu SMP Tue Mar 24 19:29:48 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
.... and the number of 'Successfully installed' packages varies and appears random.
What mono version is this ? Please use the latest version from
mono version is 4.0.0
We cannot just download latest as we are tied to latest version here https://github.com/mono/docker
Actually, that is the wrong repo, it's here https://hub.docker.com/_/mono/
Can you still reproduce with latest Docker images? If so, could you please provide us with some stacktraces of the crash?
Please reopen if you can still reproduce. Thank you.
