Hello, I got some random segfaults (while loading Seaside) with 32 bit spur vm on FreeBSD - can someone (with low level knowledge) decode attached log? Is this some problem with stack size? Can I fix this? Log: http://pastebin.com/raw/NpFUnjh0 There is "**StackOverflow**" lines n the log... Thanks! pf
Hi Petr, That looks like a bug with FreeType with our FFI. It should actually have been fixed but I donât know if the VM for FreeBSD is up to date. Can you post the output of âSmalltalk vm versionâ? Cheers, Max

The C files are generated from VMMaker and the line numbers change a lot. If you look upwards in the C file you should see a generated comment that links to the Smalltalk source it was generated from.
I need to learn a little, how to play this "core C" game in gdb... What next?
I recently learnt a bit of using gdb on the image. I'm planning to write up something but its a few weeks off. The old post How to debug the VM? [1] by Mariano needs a bit of adaption, but got me off to a good start. If you look in VMMaker package where #printAllStacks is defined you'll see some others you can call, that just print the current Smalltalk call stack.

That's not true. I develop on Mac OS X using Spur and the 32-bit VM. I do run the 64-bit system from time to time and am currently collaborating with Bob Westergaard to move the Cadence system over to 64-bits. I do hope to use 64-bit Spur from day-to-day but am not there yet, not for any reasons of deficiency in 64-bits but simply because my current, large, project-laden, VMMaker image is in 32-bits and I've not changed it over yet.
Run vm/image/buildspurtrunk64image.sh.

in fact, this is not related to FFI⦠but it should be fixedâ¦
along with the VM version, which version of Pharo are you using?

Hi Petr,
That looks like a bug with FreeType with our FFI. It should actually have been fixed but I donât know if the VM for FreeBSD is up to date. Can you post the output of âSmalltalk vm versionâ?
Cheers, Max

Hello, I got some random segfaults (while loading Seaside) with 32 bit spur vm on FreeBSD - can someone (with low level knowledge) decode attached log? Is this some problem with stack size? Can I fix this?

Petr, Based on Max's suggestion, have you tried turning FreeType off? World > System > Settings > Apperance > Use Free Type. IIUC this will fall back to using built-in Strike Fonts [1], and maybe just bypass the issue?? [1] http://pharo.gemtalksystems.com/book/LanguageAndLibraries/fonts_in_pharo/str... P.S. Just curious, in the philosophy of trimming down the Pharo Image size, are Strike Fonts a candidate for removal. It seems like having an in-Image fall back is potentially useful when porting to new platforms. cheers -ben

With FreeType off - still segfaulting. I will move this topic (+ how to debug this segfaults) to the vm mailinglist. Thanks!
