Problem with failing primitiveStringHash? | Cannot load metacello.sar

See original GitHub issue

I tried to file in this metacello.sar in two images, Squeak5.3-19448-32bit.image and a fresh 64-bit Trunk image. In each case, I get the following error message while the preamble of the SAR file is processed:

MessageNotUnderstood: ByteString>>bitAnd:
ByteString(Object)>>doesNotUnderstand: #bitAnd:

A closer look at the temporary variables causes confusion:

  • in String>>hashWithInitialHash: and below, speciesHash contains the receiver
  • in MCMethodDefinition>>hash, hash is nil
  • When I restart from MCMethodDefinition>>hash and step over all sends, the error does not occur
  • But when I restart and step over from the sender of this context (Set>>scanFor:), the error occurs again

So, is there a bug in primitiveStringHash that probably misaligns the stack variables in any way? Interesting bug …

PS: Please let me know if you can reproduce it.

So ca63f69 checks the stack after every primitive. And 4e152a6 fixes an embarrassing number of primitives that left the stack imbalanced or at least did not check argCount. Released as 1.0.1.

@LinqLover please use the vm-dev list for this kind of question/discussion. Nobody’s gonna read through closed tickets 😉
