NewVM: EXC_BAD_ACCESS in new Integer(int) #1311

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
This is part of tracking down crashes in the DataMapper library.  I'll be 
posting a more minimal case when I have narrowed it down.  Crash occurs here:

void set_field_java_lang_Integer_value(CODENAME_ONE_THREAD_STATE, JAVA_INT 
__cn1Val, JAVA_OBJECT __cn1T) {
    (*(struct obj__java_lang_Integer*)__cn1T).java_lang_Integer_value = __cn1Val;
}

EXC_BAD_ACCESS (code=1, address=0x19)

__cn1Val    JAVA_INT    16  16
__cn1T  JAVA_OBJECT 0x1 0x00000001

I believe it is line 15

That does look a bit suspect.
#define swapStack(array, sp) { \
    struct elementStruct t = array[sp]; \
    array[sp] = array[sp - 1]; \
    array[sp - 1] = t; \
}

This is effectively copying a struct which might be a problem. If you change 
swapStack to this does it solve it:
#define swapStack(array, sp) { \
    javaTypes tt = array[sp].type; \
    elementUnion td = array[sp].data; \
    array[sp].type = array[sp - 1].type; \
    array[sp].data = array[sp - 1].data; \
    array[sp - 1].type = tt; \
    array[sp - 1].data = td; \
}

I get the same result after changing swapStack().  

I'm looking through the debugger at a few break points to see I can shed any 
light on this.

I seem to get good results by changing swapStack to:

#define swapStack(array, sp) { \
    struct elementStruct t = array[sp-1]; \
    array[sp-1] = array[sp - 2]; \
    array[sp - 2] = t; \
}

I'm still playing catchup here, but I believe the stack pointer is usually 
(always??) pointing to the *next* position where something can be added to the 
stack.  Therefore swapping the top 2 items in the stack actually entails 
swapping items at positions (sp-1 and sp-2), and not (sp and sp-1).

Do you see any flaws in my logic?  If not, can I commit this?

I have gone ahead and committed this.   I've gone through it with a number of 
test cases, and I'm fairly certain that this is correct.

(At the very least it corrects this issue).

I was just commenting for you to go ahead and got a conflict ;-)
