I can't reproduce the issue here. Does it fail with seams anywhere? or do they have to be marked in a particular way? if so please provide .blend file.

I see the problem too, it seems that angle unwrap fails when trying to unwrap more than two faces at a time
This issue didn't happen a few days ago, it was possible since 2.4x to select a few faces and unwrap, without adding seams

Hi!
Here is the blend.
It only happens in "make" build. Daily build works fine.

I had to do a lot of skipping when bisecting, but seems that a35ad5899f is first bad commit.
CC @Chris_Blackbourn

I have also bisected error message displayed and this started somewhere between e8289c0aff and 6f1f2b9830

@iss i usually compile using "make update" "make release", is there a way to do a "make "un - update""? or something to build to an early state, relatively simple im not a developer, instead of the last, so i could help a bit more narrowing where the bugs started

you can git checkout sha1-of-your-choice to switch to earlier state. But there is chance it won't compile due to library updates if you go too much into past. make lite could help then.
