Hi Eliot, Folks,
I found that recent Cog VMs crash when using AndreasSystemProfiler. I'm using Cuis https://github.com/Cuis-Smalltalk/Cuis-Smalltalk-Dev , but could reproduce the problem in Squeak4.6-15078 and AndreasSystemProfiler from http://ss3.gemstone.com/ss/AndreasSystemProfiler.html . I tried on Windows 7 and Linux Debian Jessie and saw similar behavior. I could try on a Mac if helpful.
To reproduce the problem, evaluate this, several times. Usually crashes after 4 or 5 tries:
AndreasSystemProfiler spyOn:[10000 timesRepeat: [3.14159 printString]]
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.
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.
All the crash dumps are at https://www.dropbox.com/sh/juewbluobhciejh/AABjvOKULw9mZNvlVg3t8Dyga?dl=0 ..
The Linux crash files include these lines at the end:
stack page bytes 4096 available headroom 2788 minimum unused headroom 3004
(Segmentation fault)
The Windows crash files include a "Stack backtrace" and a "Smalltalk stack dump".
Thanks in advance for your help.
Regards,
Juan Vuletich
