I've just fixed it and suspect it might be the same bug that is biting you. I wonder if you can do me a favour. Can you try and construct a version of your bug that crashes without user intervention? i.e. in e.g. a workspace evaluate</div><div><br></div><div> Smalltalk snapshot: true andQuit: true.</div><div><span style="color:rgb(0,0,0);font-family:arial,sans-serif;font-size:13px"> 1 to: 50 do:[: i | Browser open]</span><br></div><div><span style="color:rgb(0,0,0);font-family:arial,sans-serif;font-size:13px"><br></span></div><div><span style="color:rgb(0,0,0);font-family:arial,sans-serif;font-size:13px">and then verify that the image crashes on startup? And then save that image (or mail me a copy)? The reason is that the bug is very sensitive to allocation order and so won't crash reliably if started from a menu pick, where the exact timing, movement of the mouse etc can all change object allocation. With the saved snapshot, however, everything is unchanged except code determined by the date the image is started in, the directory it is started in, etc. But it is much moire predictable. Once there's a reliably crashing image it is easy to check whether a new VM fixes the bug or not.</span></div><div><span style="color:rgb(0,0,0);font-family:arial,sans-serif;font-size:13px"><br></span></div><div><br></div><div class="gmail_extra"><br><div class="gmail_quote">On Sun, Oct 12, 2014 at 7:32 AM, karl ramberg <span dir="ltr"><<a href="mailto:karlramberg@gmail.com" target="_blank">karlramberg@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex"> <br><div dir="ltr">The <a href="http://www.mirandabanda.org/files/Cog/VM/VM.r3095/cogspurwin-14.39.3095.zip" target="_blank">cogspurwin-14.39.3095</a> vm crashes when I run <span style="color:rgb(0,0,0)"></span><div><br></div><div>1 to: 50 do:[: i | Browser open]</div><div><br></div><div>Crash dump attached.</div><div><br></div><div>Karl</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Sat, Oct 4, 2014 at 2:17 AM, Eliot Miranda <span dir="ltr"><<a href="mailto:eliot.miranda@gmail.com" target="_blank">eliot.miranda@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex"> <br><div dir="ltr">...at <a href="http://www.mirandabanda.org/files/Cog/VM/VM.r3095/" target="_blank">http://www.mirandabanda.org/files/Cog/VM/VM.r3095/</a>.<div><br></div><div><div>CogVM binaries as per VMMaker.oscog-eem.890/r3095<br></div><div><br></div><div>Fix line-buffered input in sqFilePluginBasicPrims.c when buffer size > 1.</div><div>fread cannot be relied upon to answer lines.</div><div><br></div><div>Fix bug in Cogit>>lookup:for:methodAndErrorSelectorInto: which if cogging a</div><div>method found through an MNU would set the cog method's selector to the original</div><div>selector that was not understood instead of #doesNotUnderstand:.</div><div><br></div><div>Fix the description of the blockonwarn flag (not blockonwarning).</div><div><br></div><div>Spur:</div><div>Fix one-way become for classes with and without copyHash, primarily by fixing</div><div>allInstances.
