The point here is that this test fails on arm with SIGBUS due to **child_stack** is unaligned:

```
bash-3.2# LSAN_OPTIONS=log_pointers=1 /build/llvm/projects/compiler-rt/test/lsan/ARMLsanConfig/TestCases/Output/swapcontext.cc.tmp fooChild stack: 0x7e9ee5f3
Bus error
```
I can align it manually or use **malloc/aligned_alloc** instead of **new[]** to avoid the issue.
