TargetAlignmentGreaterAndInputNotAligned on LBPair

[lagzda]

Hi there, I am getting the error - TargetAlignmentGreaterAndInputNotAligned whenever I try to load LbPair from program.account call on mainnet.

Any pointers?

Can you try use nightly-x86_64-apple-darwin toolchain?

Hi, @codewithgun I have the same issue on darwin though on aarch64 (apple m1 chip). All I'm trying to do is run the market_making example program. Using currently nightly causes ahash to fail to compile and I have also tried nightly-2024-01-15-aarch64-apple-darwin based on the date of your comment but still same error TargetAlignmentGreaterAndInputNotAligned. I've tried multiple pools with different tick spacing and fees as well and same issue.

Here's the trace:

I have a temp fix here. Add debug-assertions = false to Cargo.toml to solve this problem. But since this action undermine UB check on rust 1.70.0 though it should not be permanent solution.

hey folks any update on this? having the same issue attempting to parse LbPair accounts on mainnet, this is a major blocker. the proposed temp fix of adding debug-assertions = false to Cargo.toml doesn't seem to work for me either

[jake-selini]

update: did some digging and found out it's an issue with how newer versions of rust/llvm handle byte alignment - there's a number of open issues at Anchor reporting the same thing coral-xyz/anchor#3114

downgrading rust to 1.76 fixed this issue for me
