[Vm-dev] [Pharo-users] My Pharo image is crashing

[Guillermo Polito]

Hi Sergio,

I'm forwarding Eliot's answer ^^. He suggests you compile a VM with assert
flags to be able to check the output.

Maybe first you could try with the latest VM for pharo7 and see if the same
problem still happens?

Then, if you want to compile the VM in assert I can give you a hand, It
should not be too difficult (probably the only boring/time-consuming thing
is installing XCode if you don't have it).
Usually it should be as easy as going to
the build.macos32x86/pharo.cog.spur/ directory and execute ./mvm -a

Eliot,

I assume from your answer that no big changes were done on the GC since
june?
Also, I've never seen/used the leak checker before. I remember having
listened to somebody naming it, but that's all.

Do you have some pointer? Now I've found only some old emails from the
archive.
Maybe the following is enough?

$ vm --leakcheck 5 bla.image

@Sergio, could you try running the vm with this additional argument?
