Re: [hatari-devel] Possible bug in 060 exception stack frames

[Thorsten Otto <admin@xxxxxxxxxxx>]

Ok, i've added now debug output in the test program that uses NF_STDERR so it writes also on the console. Together with the debug output from Hatari, that gives:

-> somehow, the stacked pc in the exception frame seems to be corrupted (0x00100000)
