Test is failing on AArch64 linux - various machines. I did more than 20 
runs on the test infrastructure and the test is consistently failing on 
AArch64, no matter which machine takes up the job. I don't have a 
separate standalone AArch64 hardware to cross-check. Therefore I went 
down the path of the most obvious solution ...
