Closed nasastry closed 6 years ago

nasastry commented 7 years ago

Steps to re-produce:

  1. Get the device-crash-test script from qemu git under scripts folder.
  2. Run the script with default qemu binary. ./device-crash-test /usr/bin/qemu-system-ppc64
  3. Check the output ...

------- Comment From alexey@au1.ibm.com 2017-10-26 02:48:15 EDT------- I posted a patch to replace assert() with a proper error report. But this is not something we support or care, really - there is no scenario when we would consider using floppy disc.

------- Comment From lagarcia@br.ibm.com 2018-03-23 12:27:40 EDT------- It seems this has never reached upstream. Should we retry or close this bug?

aik commented 6 years ago

A similar fix has been pushed out - https://git.qemu.org/?p=qemu.git;a=commitdiff;h=b3da5513;hp=089eac81e1d34d202471c0a023284f47f4c5f00e

So this might be eventually fixed as well but we can close it anyway as it is not what we support anyway.
