Ok, I tried all the above - I now get a minimal backtrace :(

I have an identical 'clone' of this system (with the same issue) - is there 
something I can put in '/etc/make.conf' and rebuild the world [with your 
patch] with debug stuff enabled everywhere, on that clone?

It may be easier to rebuild with debug on everything, install it all, and 
reproduce the issue (knowing debug is on everywhere). I can do that leaving 
the other copy of this machine 'as-is'.

Also, if we're doing that is it worth turning off optimisation's? (If so, 
how?)
