Subject: [Qemu-devel] Abort with qemu-aarch64(latest git master)
Date: Mon, 08 Aug 2016 16:53:47 -0400 [thread overview]
Message-ID: <8760rbt21w.fsf@gmail.com> (raw)
I am seeing an abort when I run qemu-aarch64 on a multi-threaded ARM64
executable. Is this a valid use case or is multi-threading still not supported?
The back trace is as follows. You can find it as a paste for easier reading
