Thank you for your reply. The core dumping problem is now gone,
thanks to the --gung-ho switch. (What does this do?)
<gory details>
It enables the preprocessor switches -DUSE_MINIMAL_TAGBITS and
-DINDEXED_LRECORD_IMPLEMENTATION. While the type tags were
traditionally at the top of the Lisp Object, minimal tagbits move them
to the bottom (the place is free because of alignment), which means
that there are now exactly two tag bits, giving us four types --
character, record, and two integer types, which employ some trickery
to provide 31-bit integers. Indexed lrecord implementation changes
the way lrecord informatino is stored. --gung-ho will be the default
beginning with 21.2.14.

In this case, --gung-ho likely sweeps the bug under the carpet.
