[squeak-dev] Wrong method source pointer in Squeak5.2

Hi,
We have an issue in Seaside where a loaded test method holds a bad
source pointer. We only noticed because this method accesses the
debugger map.
How to reproduce:
1. clone SmalltalkCI:
git clone git at github.com:hpi-swa/smalltalkCI.git
2. clone Seaside:
git clone git at github.com:SeasideSt/Seaside.git;
git checkout 9cb54a7b14cd254ef318294905c4e8dda8dd9f79
3. install Seaside in Squeak5.2:
<path to SmalltalkCI>/run.sh --headful -s Squeak-5.2 <path to
Seaside>/.smalltalk.ston
4. Run the test WAPharoDebuggerTest>>testNamedTempAt and you'll see a
debugger pop up for an UndeclaredVariable. The source lookup is
performed in the changes file but in the middle of a chunk of binary
(font) data.
I can can only speculate that some of that binary data introduces random
chunks which messes with the offsets.
We're adding a workaround for that particular test for now.
Let me know if I can help track down the issue.
Cheers,
Max
