BUG IN EXPANDED MEMORY TI PC-SCHEME?
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? Tnx. -B
