Line numbers without corresponding function names makes it hard to tell
if I'm looking at the same place of code.  Stating which commit id you
actually tested makes the report a bit more reliable.  But in commit
612fd157, that line of vbox_tmpl.c really is after a VIR_ALLOC; at which
point I have to suspect that you are either out of memory or we have a
heap corruption bug that has corrupted the malloc arena.

Most likely, a bug, but to be sure, we'd need to know what XML string
you are passing to attach-device, and you might also want to run things
through valgrind to see if we really are smashing the heap in your
particular case.
