Re: [chuck-users] chuck under gdb?

24 May 2009

      I've recompiled chuck with -g and it just gets stranger: with a  
construct along the lines of:

fun void a() {
	<<< "in a before b" >>>;
	b();
	<<< "in a after b" >>>;
}

fun void b() {
	<<< "entering b" >>>;
	...do some stuff...
	<<< "exiting b" >>>;
}

There are no yields() that would let another process run in-between  
the call to b and returning to a, but it *sometimes* crashes after the  
return, so I see the equivalent of:

	"in a before b"
	"entering in b"
	"exiting in b"
	[crash]

I'm seeing a "KERN_INVALID_ADDRESS" at a non-zero address, thrown from  
inside Chuck_Instr_Reg_Push_Imm::execute()

I'm at a real loss how to tackle this one.  Its part of a large body  
of code, so excerpting it down to a minimal example would be tough.   
Absent any suggestions from the Chuck wizards out there, I'm tempted  
to simply re-write my code in a different way and hope it makes a  
difference.  But that's not my favorite approach.

Suggestions more than welcome.

Yeah, if you don't get filenames in gdb, you need to recompile with
-g. I thought it did that by default... maybe it's inconsistently used
across the makefiles?
