The linked NetBSD bug report http://gnats.netbsd.org/54310 now has confirmation that this crash was the result of a memory corruption bug in QEMU which happened to manifest with the newer glib version. That bug is fixed in QEMU master in commit ef905eff421c5a06a01 which will be in the 5.2 release, so we can mark this as 'fix committed'.

I tracked it down to glib's GHashTable improvements. qemu is happy with a glib built from ``` git checkout -f 2.60.4 git revert --no-edit 86c6f7e2b..3bed8a13b git revert --no-edit 75f8ec1df9b48b0c3a13a9125f2c7d7c5adf5159 git revert --no-edit 603fb5958..d3074a748 git revert --no-edit 0b45ddc55..0600dd322 ``` When the GHashTable improvements were committed, there was already a preemptive note about any breakage being due to using private implementation details, hence mentioning it here rather than with glib.
