You mean: does it actually yield a fault at run-time? Well, it doesn't
/seem/ to (i.e., I haven't identified any reproducible "bug" caused by
this), but I think it /could/. ;-)
All other such global variables are, understandably, explicitly made
non-collectable. For instance, in `srcprop.c', SCM_SOURCE_WHASH is
non-collectable because it is bound to a top-level binding. In
`symbols.c', the SYMBOLS weak hash table is made permanent via a call to
`scm_permanent_object ()'.
Thanks,
Ludovic.
