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? --- cli /CogNOS/image (master)$ ../vms/vmI61/pharo-ui Pharo.image ../scripts/loadSqueakNOSImage.st /CogNOS/image (master)$ ../vms/vmI61/pharo-ui SqueakNOS.image --- loadSqueaNOSImage.st Author useAuthor: 'LoadSqueakNOS' during: [ Metacello new baseline: #SqueakNOS; repository: 'github://nopsys/CogNOS/Image-src'; load ].
