Try running this command via strace

sudo apt install strace
sudo strace ubuntu-core-vm init edge

Keep in mind that strace is very verbose.

Look for anything suspicious before a segfault, as this may lead you to the source of the problem.

Also you can use gdb along withe core dump to analyze it.

Read about it here: https://stackoverflow.com/questions/8305866/how-do-i-analyze-a-programs-core-dump-file-with-gdb-when-it-has-command-line-pa

From your strace it seems that its' a snap package. But there are only beta and edge versions available:

sudo snap install ubuntu-core-vm
error: snap "ubuntu-core-vm" is not available on stable but is available to install on the
       following channels:

       beta       snap install --beta ubuntu-core-vm
       edge       snap install --edge ubuntu-core-vm

       Please be mindful pre-release channels may include features not completely tested or
       implemented. Get more information with 'snap info ubuntu-core-vm'.

So you should rather report a bug in this snap to its developers.
