Make sure to flush all queued emulator logger messages before starting the test. The trap_exit_badarg could sometimes leave messages and since the handler and messages now are handled in different processes this becomes a problem.

2018-12-13erts: Fix possible heap corruption getting atomicsTomas Abrahamsson
Due to comparison as a signed integer, when getting an unsigned atomic in the range 2^63-1..2^64-1 (when the most significant bit was set), the heap could get corrupted when the integer was retrieved: hsz would get set to zero, but the code proceeded to build a bignum. Steps to reproduce (at least on x86_64): $ erl 1> A = atomics:new(1,[{signed,false}]). 2> atomics:put(A,1,18446744073709551615). 3> atomics:get(A,1). At the last step, the shell would print some garbage and hang.

2018-12-13erts: Fix seq_trace:reset_trace dirty gc bugLukas Larsson
When seq_trace:reset_trace could be called while a process was doing a dirty GC. This triggered a race where all signals was moved to the internal signal queue during the GC which in turn caused the a heap overrun problem. This fix makes it so that the main and msgq lock are taken before the clear. This will make sure that we are allowed to do the clear.

2018-12-13Fix reading beyond end of bignum in integer squaringBjörn Gustavsson
The multiplication of two bignums is specially optimized when the two operands have the same address, because squaring can be done more efficiently than multiplication of two arbitrary integers. That is, expressions such as `I * I` will be calculated by squaring the value of `I`. The optimized function for squaring would read one word beyond the end of the bignum in the last iteration of a loop. The garbage value would never be used. In almost all circumstances that would be harmless. Only if the read word happened to fall on the start of an unmapped page would the runtime crash. That is unlikely to happen because most bignums are stored on a process heap, and since the stack is located at the other end of the block that the heap is located in, the word beyond the end of bignum is guaranteed to be readable.
