Comment 5 for bug 2025030

I created https://github.com/snapcore/snapd/pull/12919 to demonstrate that a combination of certain profiles lead to very large memory usage (1.6G in my test on 22.04) and that omitting it results in more reasonable memory usage (380Mb).

And I created https://github.com/snapcore/snapd/pull/12919 that changes the default to stop using "-O no-expr-simplify".
