>Description:
Following the update of emulators/qemu to 1.1.0 (shadowing wip/qemu),
I updated that package to -HEAD in my pkgsrc tree (is otherwise -2012Q1)
and built.

Attempting to run:

  $ qemu-system-i386 -cdrom /d0/build/netbsd-5/REL/iso/i386cd.iso wd0

Resulted in:

  Memory fault (core dumped)

Loading everything into gdb reveals:

Core was generated by `qemu-system-i386'.
Program terminated with signal 11, Segmentation fault.

#7  0x00000000 in ?? ()


The same result is had from 'qemu-system-sparc'.  I haven't tried any
other targets.
>How-To-Repeat:
Update emulators/qemu to -HEAD.  Build and install on
NetBSD-5.1_STABLE/i386 (other host arches? other sub-branches of
netbsd-5?).

(Was last observed to build and run fine on NetBSD-6.0_BETA2/i386.)
