Both jump to bus error address - 2 (second prefetch causes bus error)
and jump to address that causes bus error (first prefetch causes bus
error) cases tested and confirmed.
Fix is in winuae tree.
thanks a lot, corresponding patch was just pushed to Hatari tree.
Sorry, but I have to report back that the exception stack frame is still
wrong. Different, but still wrong. This is with Hatari built from commit
39523d4c.
The stacked PC should be offset 6 bytes from the offending JSR 0x401234,
as can be seen in the photo (.jpg) from a real 68000. But as you can see
from the attached .png screenshot, the PC on Hatari is now 0x415214,
offset by about 4 megabytes(!) from the offending JSR.
@Toni, @Nicolas: I'm afraid either the fix or the merge is wrong.
Regards
Christian
