Interesting. Were you running with INVARIANTS on? I got a completely
reproducible kernel panic when running your script, regardless of whether I
used -F 12 or -F 16; it was trying to write file data past the end of the disk,
and causing kernel memory pool to become corrupted. I was seeing Memory
modified after free errors, with blocks most recently used by GEOM and file
desc.

Were you running the script with INVARIANTS on?
