Hi Eliot, Folks,<br>
<br>
I found that recent Cog VMs crash when using AndreasSystemProfiler. I'm using Cuis <a href="https://github.com/Cuis-Smalltalk/Cuis-Smalltalk-Dev" rel="noreferrer" target="_blank">https://github.com/Cuis-Smalltalk/Cuis-Smalltalk-Dev</a> , but could reproduce the problem in Squeak4.6-15078 and AndreasSystemProfiler from <a href="http://ss3.gemstone.com/ss/AndreasSystemProfiler.html" rel="noreferrer" target="_blank">http://ss3.gemstone.com/ss/AndreasSystemProfiler.html</a> . I tried on Windows 7 and Linux Debian Jessie and saw similar behavior. I could try on a Mac if helpful.<br></blockquote><div><br></div><div>Thanks, its on my list.</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

To reproduce the problem, evaluate this, several times. Usually crashes after 4 or 5 tries:<br>
<br>
AndreasSystemProfiler spyOn:[10000 timesRepeat: [3.14159 printString]]<br>
<br>
This does _not_ crash in coglinux-15.22.3370 or cogwin-15.22.3370 (from June 4th). With this VM I can evaluate the expression over 40 times and never saw a crash.<br>
<br>
It does crash on the newer release: cogwin-15.24.3386 and coglinux-15.24.3386. It also crashes on the very latest cogwin-15.28.3410 and coglinux-15.28.3410. I tried on one machine with Win7 and Linux and on another PC with Win7. Results were consistent.<br>
<br>
All the crash dumps are at <a href="https://www.dropbox.com/sh/juewbluobhciejh/AABjvOKULw9mZNvlVg3t8Dyga?dl=0" rel="noreferrer" target="_blank">https://www.dropbox.com/sh/juewbluobhciejh/AABjvOKULw9mZNvlVg3t8Dyga?dl=0</a> ..<br>
<br>
The Linux crash files include these lines at the end:<br>
stack page bytes 4096 available headroom 2788 minimum unused headroom 3004<br>
(Segmentation fault)<br>
<br>
The Windows crash files include a "Stack backtrace" and a "Smalltalk stack dump".<br>
<br>
Thanks in advance for your help.<br>
<br>
Regards,<br>
Juan Vuletich<br>
