commit 7b7ab18d0b9769b5f39e663fa55caed461b1202e: Author: Michael Roth <mdr...@linux.vnet.ibm.com> Date: Tue Jul 30 13:04:22 2013 -0500 chardev: fix CHR_EVENT_OPENED events for mux chardevs Patch link: http://patchwork.ozlabs.org/patch/263458/ ** Changed in: qemu Status: New => Fix Committed -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1210212 Title: qemu core dumps with -serial mon:vc Status in QEMU: Fix Committed Bug description: qemu 1.5.2-1 dumps core when asked to put the monitor on a virtual console. For example, suppose you want to monitor the second serial port, you might try something like: qemu-system-x86_64 -serial null -serial mon:vc But that creates a core dump. In fact, even re-creating what should be the default dumps core: $ qemu-system-x86_64 -serial mon:vc:80Cx25C Segmentation fault (core dumped) I'm not including a backtrace because the bug is so easy to reproduce, but I can provide more info if necessary.
