Ok, looks there's just ppc64 in the compile farm. Running on gcc110, asan.exp
works all fine except c-c++-common/asan/swapcontext-test-1.c.

I also verified that w/ -m32, shadow memory in properly prepared:

=>0x3ff758e0: 00 00 f1 f1 f1 f1 00[04]f2 f2 f3 f3 f3 f3 00 00

If you have a reduced test-case, I can help.
