pharo64+git crash

melkyades
Hi, I wonder if I'm doing something wrong or using a wrong version:

I download a pharo image (spur64) from 

http://files.pharo.org/get-files/61/pharo64.zip

and a 64 bit vm from:


Then I try to load a git repo like this:

./pharo Pharo.image ../scripts/loadSqueakNOSVM.st

where the script just says 

"Based on the same file from the pharo-vm project"

Author useAuthor: 'LoadVMMaker' during: [ 
Metacello new
        baseline: #Nopsys;
        repository: 'github://nopsys/CogNOS/VM-src';
        load ].

(Smalltalk saveAs: 'generator') 
    ifFalse: [ Smalltalk snapshot: false andQuit: true ].

and it crashes with the log pasted below. I cannot even load the code, any clue?

Cheers,
Pocho

Hi Javier,

can you try with a 64 bits Pharo 7 vm (http://get.pharo.org/64/vm70)?
The Pharo 6 64bits vm used to have segfaults upon code loading.

Regards,

Thierry

Re: pharo64+git crash

Didn't work. Tried also with vmT70 and vmI70 and neither did work. Sometimes they segfault, sometimes they hang using 100% cpu. I noticed that being for pharo7 those vms seemed pretty old (aug-2017), so I tried vmTLatest70 and that one finally worked.

Oh :( Thank you for pointing that it worked with the latest 70 vm.

I must admit that I'm using directly downloaded recent vms to avoid that
same segfault and not the pharo.org VMs, but the process for setting
them is a bit complex. So I hoped that the problem was solved with the
Pharo 7 VMs, which are newer.

Re: pharo64+git crash

EstebanLM
I think I will declare new stables today. 
this is becoming a too confusing, and latest VMs are working fine, AFAIK ;)

Didn't work. Tried also with vmT70 and vmI70 and neither did work. Sometimes they segfault, sometimes they hang using 100% cpu. I noticed that being for pharo7 those vms seemed pretty old (aug-2017), so I tried vmTLatest70 and that one finally worked.

Oh :( Thank you for pointing that it worked with the latest 70 vm.

I must admit that I'm using directly downloaded recent vms to avoid that same segfault and not the pharo.org VMs, but the process for setting them is a bit complex. So I hoped that the problem was solved with the Pharo 7 VMs, which are newer.

   Hi Javier,
   can you try with a 64 bits Pharo 7 vm
   (http://get.pharo.org/64/vm70)? The Pharo 6 64bits vm used to have
   segfaults upon code loading.

       Hi, I wonder if I'm doing something wrong or using a wrong version:
       I download a pharo image (spur64) from
       http://files.pharo.org/get-files/61/pharo64.zip
       <http://files.pharo.org/get-files/61/pharo64.zip>
       and a 64 bit vm from:
       get.pharo.org/64/vm61 <http://get.pharo.org/64/vm61>
       <http://get.pharo.org/64/vm61>
       Then I try to load a git repo like this:
       ./pharo Pharo.image ../scripts/loadSqueakNOSVM.st
       where the script just says
       "Based on the same file from the pharo-vm project"
       Author useAuthor: 'LoadVMMaker' during: [
       Metacello new
                 baseline: #Nopsys;
                 repository: '<a href="github://nopsys/CogNOS/VM-src" class="">github://nopsys/CogNOS/VM-src';
                 load ].
       (Smalltalk saveAs: 'generator')
             ifFalse: [ Smalltalk snapshot: false andQuit: true ].
       and it crashes with the log pasted below. I cannot even load the
       code, any clue?
       Cheers,
       Pocho
