Yes there is "PharoVMBuilder buildFreeBSD", but some "cog*" errors occurs... So I am still building with "PharoVMSpur32Builder buildUnix32" under Linux (CentOS6) and then move compiled vm to my FreeBSD box with Linux compatibility layer. I compiled DEBUG vm version according to your advice and this is gdb output: Program received signal SIGSEGV, Segmentation fault. 0x080aefc1 in scavengeReferentsOf (referrer=684415032) at /home/pf/pharo/pharo-vm-debug/src/vm/gcc3x-cointerp.c:39014 39014 if (((longAt(referent)) & ((classIndexMask()) - (isForwardedObjectClassIndexPun()))) == 0) { I need to learn a little, how to play this "core C" game in gdb... What next? A also compiled PharoS (Pharo Stack) VM, and it's 5x slower, but stable, there is no stack errors (or other crashes) like in cog spur vm. pf
You could build a debug VM from here https://github.com/pharo-project/pharo-vm I also glimpsed some FreeBSD build options there you might try. cheers -ben

So... I compiled latest sources (blessed) on CentOS 6.8, fine, moved compiled binaries to FreeBSD and tried to load Seaside to the latest 50760 image. Still stack errors, log here: http://pastebin.com/raw/bf1EpWNt
When I run this on CentOS, everything is fine (loading Seaside, no stack errors), but when I run the same on FreeBSD, stack errors (segfaults) occurs.
So... There is something bad on FreeBSD side? Can I debug more?

Try 50760 from... http://files.pharo.org/image/50/

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?
Log: http://pastebin.com/raw/NpFUnjh0
There is "**StackOverflow**" lines n the log...
Thanks! pf
