duplicate of https://github.com/rust-lang/rust/issues/112332

pushkar85 commented 1 year ago

@lukas-code is there any work around , currently its completely broken

lukas-code commented 1 year ago

The bug seems to be fixed in rkyv 0.7, so if you can upgrade that would probably be the best solution.

Otherwise, if you're stuck with rkyv 0.6, you can hack around this by disabling the buggy optimization pass by setting these environment variables:

RUSTC_BOOTSTRAP=1 RUSTFLAGS=-Zmir-enable-passes=-Inline

(Note that this enables unstable options on the stable compiler and isn't really supported.)

Thanks a lot @lukas-code , for now it has worked

pushkar85 commented 1 year ago

@cjgillot by when we can expect this patch to be included in rust 1.71

@lukas-code This workaround does not work , when any optimisation level is set .
