I know sparc64 had little chance of actually working but
I thought I'd take it for a spin with 0.15.0-rc1 and
see how it fared in addition to macppc which has a good
chance of working nowdays with modern QEMU. Lets see
what QEMU and related bugs are left..
I noticed the bootblocks for each respective arch are
failing in a very similar manner. I would guess that
this is most likely a bug with the OpenBIOS Open Firmware
implementation?
Any assistance with this? Blue?
After a little playing around I have found this is definitely
a bug in QEMU. Turning on the OpenBSD malloc S flag which is
what I run on all of my systems triggered this behavior in QEMU
and trying to narrow it down further since S is a combination
of other flags I found it was the J flag specifically that is
triggering this behavior.
From malloc(3)..
J ``Junk''. Fill some junk into the area allocated.
Currently junk is bytes of 0xd0 when allocating; this
is pronounced ``Duh''. :-) Freed chunks are filled
with 0xdf.
