While working on CMake I ran the core unit tests in release mode on an Android emulator running in x86(32bit) mode. Four tests fail like this:

Realm version: 2.3.0 with Debug Disabled
Encryption: Enabled at compile-time (always encrypt = no)

REALM_MAX_BPNODE_SIZE = 1000
REALM_MEMDEBUG = Disabled

sizeof (size_t) * 8 = 32

Compiler supported SSE (auto detect):       No
This CPU supports SSE (auto detect):        None
Compiler supported AVX (auto detect):       No
This CPU supports AVX (AVX1) (auto detect): No

FAILURE: 4 out of 1066 tests failed (8 out of 13243936 checks failed).

Everything works as expected in debug mode.

I just tried on with an ubuntu32 box on vagrant and it works fine, both in debug and release mode.
