Great stuff! I now know when it is caused . . . if not precisely why. ;-)
It is, as I suspected, caused when the JIT is enabled but direct memory is
not. I see from your config, etc. you are allocating 128MB of ZIII memory.
This causes NATMEM to fail, because glibc cannot allocate a shmem segment
that large (32MB is the max). Try running UAE with 32MB of ZIII memory to
confirm this, please.
Thanks for all your hard work testing this . . . Sorry. I should have realized
what was causing this sooner.
I've been meaning to rewrite the direct memory stuff to use mmap() and friends
rather than shmget() etc to overcome this limitation. First, though, I'll see
if I can sort out what's causing the P96 problem when NATMEM is diabled.
Cheers,
Rich
