I have tested the build with gcc-10 but the problem remains, so it's not a compiler
issue. Dropping the patch rand_init-fix-off-by-one-error.patch that was introduced
with 3.0.2-3 doesn't help either.

So, we need a backtrace to see where the crash actually happens. I assume it's in one
of the build dependencies.
