<p>Hi all,</p>
<p><br>
</p>
<p>while updating one of my images today, in which I have enabled the "cache source files" preference, I stumbled upon a scanner error from <span>CompiledMethod>>#timeStamp because a method had an incomplete preamble like:</span></p>
<p><span><br>
</span></p>
<p><span><span>HTTPClient class methodsFor: 'utilities' stamp: 'mir 2/2/2001</span><br>
</span></p>
<p><span><span><br>
</span></span></p>
<p><span><span>Starting at some point in the mid of the update, this error occurs reproducibly (I discarded and re-applied the update a few times) for different methods, so somewhere there must be a wrong offset in the cached source files. If I turn off the
preference before installing the updates, no errors are raised.</span></span></p>
<p><span><span><br>
</span></span></p>
<p><span><span>Unfortunately, I do not really have an idea where to start searching for the cause of this error.</span></span></p>
<p><span><span><br>
</span></span></p>
<p><span><span>But Marcel mentioned a potential hint recently [1]: CompressedSourceFiles does not have a converter. Could this lead to this error? Dave, Marcel, do you have any ideas where to start? :-)</span></span></p>
<p><span><span><br>
</span></span></p>
<p><span><span>Best,</span></span></p>
<p><span><span>Christoph</span></span></p>
<p><br>
