Ciao,

just for the record, because I think that it is
unlikely that I or someone will succeed in fixing it.

It appears to me that there
is a problem in 'scm_malloc_reregister()', file
"libguile/debug-memory.c", which is invoked by
'scm_gc_realloc()' only when Guile is compiled
with 'GUILE_DEBUG_MALLOC' defined.

It tells me that I am trying to reallocate a block
with a different "what" string.

It comes and goes, but for the small code
evolution span in which it was reproducible: I was
able to determine that I was using the same
"what".

I circumvented it, it seems, by using the same
"what" in two different invocations to
"scm_gc_realloc()".

Understanding what is going on requirers
understanding the hash table handling, which is
a little mess IMHO, and it is above my head now.
