Comment (by sergv):

 After quite some trial and error I figured out why debug RTS works and
 release doesn't. It boils down to `gcc` compiler optimizations that RTS
 was compiled with - deubg is build with `-O0` and release with `-O2`. If I
 build debug RTS with `-O2`, `-O1` or `-Og` then I can reproduce the crash
 as well. However, the exact cause of the problem is not known yet.
