On "long" simulation runs (20+ minutes on a 12mHz 286 with LIM 4.0 EMS...) using PCSEXP, the _expanded memory_ version of Texas Instrument's PC-Scheme, I apparently run low on space, the gc starts thrashing around, and finally I get a Scheme reset because the system is out of space. Problem is, I can't find anywhere near enough current structures to fill memory. Moreover, (freesp) returns 400K + of memory, then if I invoke (freesp) again (or anything else...) it triggers another gc and sometimes another Scheme reset. I don't have the problem when I use PCSEXT and jumper my expanded memory to act like extended. Looks like (freesp) can see a big chunk of free space, but the gc isn't adding it to the free list. Anyone else had this problem with PCSEXP? Anyone have any workaround suggestions?
