How to see primitive source these days:
The code is in the VMMaker repository 'http://source.squeak.org/VMMaker'.
For the Spur VM, the package is 'VMMaker.oscog'. For purposes of just taking a quick look at the code, you can load the latest version VMMaker.oscog-eem.2079 (this will not exactly corresponding to the version you are running but here I assume you just want a quick look at what primitive 105 is doing).
To find the numbered primitive, see CoInterpreter class>>initializePrimitiveTable, which calls StackInterpreter class>>initializePrimitiveTable, which shows primitive 105 as #primitiveStringReplace.
The Smalltalk code for this primitive is InterpreterPrimitives>>primitiveStringReplace. The generated C code for this can be found in the GitHub repository https://github.com/OpenSmalltalk/opensmalltalk-vm, look for the primitiveStringReplace function in opensmalltalk-vm/src/vm/gcc3x-cointerpmt.c.

I'm was copying a FloatArray and it seems not to be using the primitive to move the data over to the copy. Float>>replaceFrom:to:with:startingAt: says it uses a primitive, but it seem to fallback to the code in SequenceableCollection. How can I see the priitive code to see what the issue may be? This is what it says it does:
replaceFrom: start to: stop with: replacement startingAt: repStart "Primitive. This destructively replaces elements from start to stop in the receiver starting at index, repStart, in the collection, replacement. Answer the receiver. Range checks are performed in the primitive only. Optional. See Object documentation whatIsAPrimitive." <primitive: 105> super replaceFrom: start to: stop with: replacement startingAt: repStart
This is what I did to see if the prim failed:
replaceFrom: start to: stop with: replacement startingAt: repStart "Primitive. This destructively replaces elements from start to stop in the receiver starting at index, repStart, in the collection, replacement. Answer the receiver. Range checks are performed in the primitive only. Optional. See Object documentation whatIsAPrimitive." <primitive: 105> WOOPS ifNil: [ WOOPS _ #WOOPS. self halt ]. super replaceFrom: start to: stop with: replacement startingAt: repStart
And it did fail and I'm puzzled as to why:
