Out of memory?

[mengstr]

I'm currently building a 24-bit SUBLEQ machine in discrete TTL logic but this architecture also intrigues me a bit and I wanted to see how much more inefficient it is compared to the already bad subleq. (It feels like if should be really bad considering it dosen't have any conditional jump as subleq, but maybe that doesn't affect it that much?)

But when tried the sieve demo it seems to run out of memory on my machine. Python is not one of the languages I code in so I really don't want to go down that rabbit hole and try to figure out what the error message really means and how to fix it.

Is there anything I can do easily?

prime_sieve.fj is in the main branch, and was added after release 1.2.0 (the latest pip install).
The main branch contains a bugfix the the problem you got, which indeed is (was) a bug.
It will be available in the next release, yet if you want to try it now - just clone my repo, and "pip install -U -e ." From the repo directory, and then you"ll have the latest code, which will successfully run prime_sieve.fj :)

Thanks, that's definitely an easy enough solution :) I will try it later today.
