I am having problems getting my code to work on a 3.5 OS Emulator. I
was looking over this discussion from a while back and I have tried
some of the tips suggested but I'm still getting a bus error on the
3.5 EZ Debug ROM. I run my app on the color (non-debug) ROM and I
don't get the bus error. Any ideas what could be going on here?
The problem usually occurs in this code:
if ( ucode & lmSetLabelUC ) {
CategoryGetName(CurrentListDB, CurrentCategory, CategoryName);
CategorySetTriggerLabel((ControlType*)LMGetObjectPtr(ListCategoriesPo
pTrigger),CategoryName);
}
The call to CategorySetTriggerLabel is crashing. Other times I am
getting the error on the following line:
WinEraseLine(lTypeCoords);
where
#define lTypeCoords 2, 143, 10, 144
which is what led me to this old discussion.
Thanks for the help.
