Testsuite fails on ppc64el about context

[jcowgill]

For good measure, running ec fails with:

These are probably related to each other though.

are you sure? commit 93da162 only increases the stacksize from 64kB to 128kB
unfortunately I've no access to a PowerPC system - could you do a git bisect?

ty, I'll take alook at it

unfortunately I've no access to a PowerPC system

I am successfully using qemu to emulate PowerPC and other architectures in my CI setup. This also works inside docker containers (expect for multithreaded programs). Maybe this is applicable for testing boost.context. Let me know if I can help.

@chfast: could you run the unit test (run b2 in sub-directory test) at your PPC64 setup?
