It fails in ~33% of the test runs with the following log:
Exception: Error: FAIL: 'x' setter was not called.
It seems it is a DFG JIT bug, because it passes always with
the same configuration and additional useDFGJIT=false
Just to document, I skipped it on AArch64 Linux:
This failure isn't exhibited anymore. I'll close the bug once the skip directive is removed.
