Comment(by Mikolaj):

 About -debug assert failure, I was doubly wrong: it's a segfault (illegal
 memory access) while computing the assertion and it's caused by using a
 leftover rts_debug library in /usr/local, from an earlier registerized
 build of 6.12.3. It appears, there is no rts_debug in my unregisterized
 build, since after cleaning /usr/local and reinstalling I see when
 compiling with "-debug -v":
