Fix compile fails and crashes on `aarch64`

[hpretl]

We have tested the proposed changes on x86_64 and aarch64, they work for both; we suggest merging them into the source.

This is the Dockerfile that has been used for testing:

# REPLACE "aarch64" BY "x86_64" IF NEEDED

thank you for contributing. To accept third party contribution I require a signed contributor license agreement to ensure we can continue to use OpenVAF in commercial settings aswell. Please download and sign CLA and send it to pascalkuthe@pm.me.

@pascalkuthe I have no issue with signing the CLA, but I need to do this on behalf of my university, which means a full round of legal reviews. For the changes under discussion, this is overkill. I propose we cancel the PR, and you just adapt the 3 tiny locations yourself. Agree?

[pascalkuthe]

sure that sounds good to me, thank you!

I was going to fix this myselfy originially but you were faster with your PR

[pascalkuthe]

I am currently finishing up the noise integration into OpenVAF which requires very larg changes.

I hope to wrap that up in the next couple of days I will push the fixes once I am done with that to avoid too much juggling of conflicting changesets

[hpretl]

Excellent, looking forward to having noise in the sims 😀👍
