Thank you for hints, Matt. And thanks for promptly fixing the problem with
"unused" function trap_is_smap(). :)

Indeed, you're right, I'm using custom kernel config. Basically, it's
GENERIC with removed all the entries that can be loaded from a module. And
of course, debugging stuff commented out, as you've mentioned. See attached
diff.

Nevertheless, I've first tried to put debugging stuff back to my custom
kernel, and then I've tried to compile and use GENERIC. But neither
approach solved the problem, the system still freezes when compton starts.
The only thing that helps, is reverting previously mentioned commit
536555a+.
