Hmm, I can't repro on the given changeset in either 32 bit or 64 bit.

(In reply to comment #1) > Hmm, I can't repro on the given changeset in either 32 bit or 64 bit. Tested on Linux 32-bit, but if it continues to be unreproducible, perhaps WFM then.

I still can reproduce this on JM changeset fd1abc43d698 with -m, -j and -n on a 32-bit Linux shell when the testcase is passed in as a CLI argument.

GCC on 32-bit Linux didn't like the uint64 cast. If returnData was 0xffff0007, rvalBits ended up with 0xffffffff type tag. I also swapped the operands because I think it's more readable now that we use (uint32). This fixes the test in coment 0 and most jit-tests (one failure left).
