Ah, looks like FreeBSD shm objects do not get extended by writes:

Writes do not extend shared memory objects, so ftruncate(2) must be
called before any data can be written.

I switched to an actual temporary file in bc262ff93e559c2f0b6da70557d3bec63173d520, see if that helps.

Thanks. Works fine now, so I've packaged for FreeBSD. Packaging status
