I thought we were told not to use this.

circle ci is using an ancient version of z3, 4.8.7, released in 2019. That's probably why adding this line causes it to fail. For the gh one, you need to update the cache action. Also, why do you have both circle ci and gh actions running?

Oh whoops - I did not mean to push that. That is stuff I usually add locally so that tock-veri-asm checks faster. I'll patch it now.

The GitHub z3's version is also a tiny bit old (4.10.2 released in 2022)
