I found out what makes it break.

Thanks. There was a bug in the log2 calculation for storing the ivar
offsets that worked at O0 because of wrapping behaviour when we
truncated the value to 32-bit, but triggered undefined behaviour that
allowed the optimiser to remove a check. The tests are now all passing
for me in release and debug configurations.
