pharo64+load code=broken image

Hi folks, I take a fresh Pharo6.1 (spur64), load a git repository and save the image. When reopening I get a segmentation fault. OS is ubuntu 17.04/64 bits. I just cannot make it work, tried with all the vms I could (vmI61, vmT61, vmLatest70, vmTLatest70). I suspect it is related to using git but I'm not even sure.

Below I put the involved code, crash dump at the end (seems to be the same with any vm). btw, the vmILatest70 script does not seem to work (curl https://get.pharo.org/64/vmILatest70 | bash).

Any ideas?

Re: pharo64+load code=broken image

Hi Javier,

what does the crash.dmp file say? Or what does a gdb stacktrace say?

Hi Eliot, the crash.dmp shows what I put in the first mail, gdb shows some more info:

As it is just loading, I think that it is trying to free some memory that was allocated before the image was saved. Looks like there is an external address that should have been niled but for some reason wasn't.

printing all stacks gives more clues: looks like we are causing an mnu at startup, I'm not sure yet why that ends in a crashed image. Maybe it happens too soon during initialization.

As it is just loading, I think that it is trying to free some memory that was allocated before the image was saved. Looks like there is an external address that should have been niled but for some reason wasn't.

Re: pharo64+load code=broken image

fixing the mnu makes the crash go away :). I still wonder if the crash is "expected" or shouldn't happen.

printing all stacks gives more clues: looks like we are causing an mnu at startup, I'm not sure yet why that ends in a crashed image. Maybe it happens too soon during initialization.

As it is just loading, I think that it is trying to free some memory that was allocated before the image was saved. Looks like there is an external address that should have been niled but for some reason wasn't.

I can take a look at the image in the simulator and/or debugger and see if any stale pointers exist. Put the image and changes somewhere where I can download them.

what does the crash.dmp file say? Or what does a gdb stacktrace say?

I'm using the following VM on Ubuntu 16.04 without any issues:

Thanks! I'll try to do something better instead: do it by myself asking questions if needed, it might take some time before I start though.

Cheers,

Pocho
