Hi Nicolas,


I could not reproduce the problem in a fresh trunk image after 12 attempts. How often do you need to recompile the image in order to experience the error, by average?


Best,

Christoph

Betreff: [squeak-dev] Error selector changed

Hi all,
>From time to time, (Compiler recompileAll) fails because some selector
identity changed...

Indeed, following snippet should always be true, but is sometimes false:

    selector == (Symbol findInterned: selector asString).

In such case, I can attempt a doIt and continue:

    selector beWritableObject; becomeForward: (Symbol findInterned:
selector asString).
    oldClass methodDictionary rehash

Sometimes I'm tempted to integrate the workaround directly in code,
but it would just mask a problem. Any clue on how this can happen?

Nicolas
