panic: kernel diagnostic assertion "fli->fli_trans_cnt > 0"

[Lloyd Parkes <lloyd%must-have-coffee.gen.nz@localhost>]

Kia ora,
I am running 11.99.4 built on Nov 22 on my amd64 and I can reliably 
panic it by building shells/bash in pkgsrc.

I have a fresh CVS checkout of pkgsrc on local disk and I have my 
distfiles automounted from a NetBSD 10.1 file server. It looks like the 
build gets as far as looking at one of the patch files and then panic. I 
can also reproduce this on a Xeon build box running 11.99.4 built on Dec 
15.

Is this something that has been fixed? Does anyone know what is going on?

The full traceback is below.

Ngā mihi,
Lloyd
