wh-sandbox have no --enable-checking but I did equivalent (set
safety to 3) by hand.  The build now finished.  After looking
at testsuite results and generated .pht pages the only errors I
see are expected ones: few triangular set examples and stream
of primes.  I saw them before -- it looks that safety 3 disables
tail call optimization and some inputs may run out of memory
or stack space.

The problem I saw looks like memory management problem and I am
not surprized that changing safey to 3 makes it go away...

BTW: in revison 513 I have fixed all errors that showed during
build with safety 3 (except for above mentioned running out of
memory).
