Squeak crash

 
Hi,

I've built my own version of Squeak (with a personal plugin) and when I've
launched it, I can see the environment but after 5 sec Squeak crashes.

Segmentation fault

You'll need to supply a bit more information. mac, windows, unix?
what steps (detailed) did you take to build the VM

Yes sorry, I use the lastest unix vm. And I use the classical way to build
I've created a src dir with the vmmaker (the lastest version).
I've generated a few numbers of plugins and do the classical ./configure; make.
Oh yes I've forget I use a pharo image the pharo0.1-10250dev09.03.2

Well assuming you have build a closure based VM, then you should turn  
on the balance checks.
change in the  interp.c  also ensure the gunified interp.c has the  
change

#define DoBalanceChecks 0
to
#define DoBalanceChecks 1

If you see in sysout

"Stack unbalanced after"

The you are guaranteed a VM crash with the closure VMs
