It looks from this bug that we fixed the initial ADOX bug in commit c53de1a2896cc (2013), and I've just tried the 'qemu-denorm-problem.s' test case from comment #1 and it works OK, so I think we've fixed that denormals bug too. Given that, and that this bug report is 4 years old, I'm going to close it. If you're still having problems with recent versions of QEMU, please open a new bug.
