The QEMU project is currently considering to move its bug tracking to another system. For this we need to know which bugs are still valid and which could be closed already. Thus we are setting older bugs to "Incomplete" now. If you still think this bug report here is valid, then please switch the

Thanks, this helps a lot! We will now check the code again and see what causes the behaviour. Fabian -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1856837 Title: qemu 4.2.0 arm segmentation fault

Can you provide a repro case (attach binary/etc to the bug) so we can investigate? Note that QEMU will produce that segfault message both for bugs in QEMU (where it unexpectedly segfaults) but also for bugs in the guest binary itself where we're correctly emulating "guest did something causing a s
