Try setting a catch throw in gdb before running ART.
Regarding libraw, it’s an optional dependency. If no suitable version is found, art will be built without it… I guess that’s what is happening in your case. If not, I have no clue 
Here is the output of ldd on the art executable from my debug build:
I don’t see libraw in the list at all

Amazingly, I guessed right it seems 
Reading symbols from ./ART...
(gdb) catch throw
Catchpoint 1 (throw)
(gdb) r

Does it stop there or does it run until it reaches the catchpoint? In the latter case, you can try printing a backtrace, maybe you get something more informative… otherwise, I don’t know what is going on, sorry…
its stopping there. WIthout the catch throw it runs but then the bt isn’t useful. Seems pretty weird to me!

Maybe your problem is related to the crostini container somehow?
