I had issues with squeak on Ubuntu (my vm builds were affected by ubuntu libraries) so I asked about it on askUbuntu. I really don't know if they are related and some may think so, since you are calling the os.

indeed I do thats what alpha+vmLatest means, latest unstable image (pharo 5 in this cage) and latest stable vm yes I am not worried about the fix, I am just reporting the problem. I can live without it for now its no big deal.

Esteban warned that things will get quite unstable in the coming days, esp. around FFI ... You best use an older version then.

additionally after pharo freezes it shows a 25% cpu consumption steadily, so maybe this some kind of memory leak, infinite loop thing ?

Re: [Pharo-users] Someone broke startup scripts on ubuntu

ok I think , and thats an assumption, the new FFI may be to blame here. navigating through all the code to find exactly the low level stuff it leads me to OSEnviroment getEnv: which is what it uses to get the low level stuff enviroment variable data , so far so good the source is ^self ffiCall: #(#String #getevn #(#(String #string)) module: LibC and once again so far so good, but if I try to right click and choose versions so I see when this method has been modified, it freezes my image every single time. So something really weird goes on with the new FFI , if its the new FFI or not something else.

"Do you have the sources file ? (PharoV40.sources)" just for the record it used to work fine, and I have done nothing to my system. If you use the command I posted you will see it installs everything it needs. "Some of these seem to be resolved through environment variables that you might not have. Read the comment for UnixResolver>>#xdgUserDir: And no, I don't know why this is implemented that way. Apparently they are following some standard." and I repeat once again , that it used to work fine. I look at the source code and trying to navigate through it froze my image.

Some of these seem to be resolved through environment variables that you might not have. Read the comment for UnixResolver>>#xdgUserDir: And no, I don't know why this is implemented that way.
