Bug#1015123: latex-cjk-chinese-arphic: FTBFS: E: Build killed with signal TERM after 150 minutes of inactivity

Some observations:

Going back to fontforge version 20201107~dfsg-4 and its dependencies, I notice the following warning message:

21900/1114292:

A more recent version of Fontforge will just let the application hang.

I will have to contact upstream to figure out what is causing this.

Very interesting; font bkai gets stuck during the fontforge compilation at 21900/1114292 and stays at 100% CPU usage. Other fonts seem fine.
This requires a bit more investigating. My gut tells me the recent fontforge upload has a regression somewhere.

Hi,

During a rebuild of all packages in sid, your package failed to build
on amd64.
