And of course, the fault was that my task was using the code and data segments of its parent (remember it will die before the task) which will be invalid immediately when the parent exits. Dan Riley kindly confirmed my suspicions, thanks Dan. Dan also suggested either seglist splitting or LoadSeg(). I'll probably try the seglist splitting method (I think Leo used this in Robotroff). Anyway, fish disks proved their usefullness, again. > >BTW, has anyone found a way to use SDB on tasks? > This question is still valid. I know that Manx db can debug tasks, but my Assembly literacy isn't too good. I'd much rather use SDB, but I haven't found any hint for this in the documentation. - Kari Sutela - lk-kari@fintuvm.utu.fi (internet) OR lk-kari@fintuvm.bitnet (bitnet)
