kodi build failing in raspbian, segfault

[peter green <plugwash@p10link.net>]

While trying to build kodi in raspbian bullseye-staging, after working around the font build issues I am running into a segfault from jsonschemabuilder. It looks like it's segfaulting before even reaching main, possibly due to some issue with static initalisation order. I got a backtrace but it wasn't hugely meaningful.

Program received signal SIGSEGV, Segmentation fault.

Anyone have any thoughts on this? if I can't find a fix I may end up having to remove kodi from raspbian bullseye.
