Device: Raspberry Pi 2

If I run ./run.bash (in src), I get:

I'm not sure if there is much we can do here. The machine is out of resources.

Marking as 1.6 to consider disabling the test on small machines, if possible.

Should I run the tests with GOMAXPROCS=1?

I'm not sure what you are asking. What is your goal? If you just want to verify that your build works, run
go test -test.short runtime

Marking as 1.6 to consider disabling the test on small machines, if possible.

It (i.e. the all.bash) fails on ~ quad-core arm7 CPU / 1GHz / 736M free RAM. I wouldn’t say it's a small or an uncommon ARM machine ...

BTW the test escapes the output t.Fatalf("expected %q, but got %q", want, got) and makes it unreadable.

I'm not sure if there is much we can do here. The machine is out of resources.

Which resources? Looks like it is not the OS 'fork-bomb' protection:

Looks like on a quad-core armv7 CPU the test exceeds the max stacksize 8192k.
('ulimit -s unlimited' let's it pass)

EDIT: sorry, scratch this comment, the test was run with the go1.4.2 in PATH

And even more weirdness: 'ulimit -s /anything else than 8192/' let's the test pass, but then it occasionally fails with an another error.

A closer look reveals, that the c code tries to create 100 threads * 8M default stack size and the runtime adds another 150-200 threads * 8M stack. That's outside the usable 32-bit virtual memory (CONFIG_VMSPLIT_2G=y) and the subsequent pthread_create fails.

IMO, the test should just lower the default stack size or the test+runtime should create less threads.

runtime: skip CallbackGC test in short mode on linux/arm
9840042 
Fixes #11959
Fixes #12035

Skip the CallbackGC test on linux/arm. This test takes between 30 and 60
seconds to run by itself, and is run 4 times over the course of ./run.bash
(once during the runtime test, three times more later in the build).
