Here the simple method:
at: index
<primitive: 60 error: x >
^ x
And its bytecode:
<primitive: 60 error: x>
13 <81 41> storeIntoTemp: 1
15 <11> pushTemp: 1
16 <7C> returnTop
Now, if i add this:
at: index
<primitive: 60 error: x >
[:foo | 5].
^ x
I get following bytecode:
<primitive: 60 error: x>
17 <81 42> storeIntoTemp: 2
19 <8F 01 00 02> closureNumCopied: 0 numArgs: 1 bytes 23 to 24
23 <20> pushConstant: 5
24 <7D> blockReturn
25 <87> pop
26 <12> pushTemp: 2
27 <7C> returnTop
so, if we ignore the block closure bytecodes, we have:
<primitive: 60 error: x>
17 <81 42> storeIntoTemp: 2
26 <12> pushTemp: 2
27 <7C> returnTop
The problem is that for method context there are only 2 temps
(argument + error code) .. but not 3 (index is zero-based).
The fix should be simple.. in code which calculates the temp index for
'error code' temp.
