The luatex core dump (both on freebsd-amd64 and linux-amd64)
is due to a metapost bug (without any diagnostic messages).
I do not believe that it is related to the recent updates
but rather to a (recent) error in my coding.

Taco may want to chase this, but I will need to provide him
with a reproducible minimal test file...
Just as an indication, I found two big errors in my metapost code:
1) a typo resulting in assignment to an array element of an undeclared array;
2) reference to a loop variable outside of a loop
(which, of course, does not work).
I believe that the core dump was due to the first mistake,
but I cannot reproduce it simply.
