[Qemu-devel] [Bug 1210212] [NEW] qemu core dumps with -serial mon:vc

[David Mazieres]

Public bug reported:

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.
