Errors in debugging

[ncannasse]

• break in CaraSlotGroup.makeIcon if( isP...) { block --> Error assert in variable names
• can't cast error (runtime) doesn't give good toplevel stack ?

CaraSlotGroup can be reproduced with OPW r1111

Fixed partially but parameter it doesn't show up when breaking on first line of makeIcon. That's because it's recast from T, and the compiler doesn't then output the correct "ARGS it:-1" output as it should.
