valgrind log

> 1. See if changing your locale has effect on the crash.

I've tried with C locale, got same result. Also, I tried different kernel
versions, just in case it has something to do with recent cpu vulnerability
fixes, but it's also not the case.

I'm not competent enough to use valgrind correctly, but it's interesting that
running 'valgrid ./ut-bin' gives SIGILL fault rather than SIGSEGV. Also, fault
in Core.so (game component), but it works fine with game's built-in software
renderer (SDLSoftDrv.so)

> 3. Try git bisect.

Bisecting this involves lots of cross-compiling, unfortunately I cannot afford
it right now :(

> Unreal.log shows that it crashed while glGetString(GL_EXTENSIONS).

Too long GL extension list was definitely a problem a some point, but there are
plenty of fixed OpenGLDrv.so libraries all over the Internet (they explicitly
have it mentioned in changelog). I tried all of them I could find, no changes.
