This happens already with:

[�� :h :s :v |�� | min chroma hdash X red green blue | ] sourceNode

I will check�� it is a bug in the mapping pc -> AST.

That's interesting, the way the pc is mapped to the AST (ir instructionForPC: )

takes the "length" of the instruction bytecode into account and the length of a pushclosure includes

all bytes needed for the pushing the local temps (pushConstant nil. pushConstant nil ....)

But the startPC of a block context starts at the first push, not after, that means

self method sourceNodeForPC: self startpc - 1

starts the search after the push closure bytecode but before any push local temp byte code.

Either we don't include the bytecodes for the "pushConstant:nil" in the bytecode offset, or we start the search at

self method sourceNodeForPC: self startpc - 1 + self numLocalTemps
