`panic_unwind` is not compiled with this crate's panic strategy `abort`

Greetings!

I'm learning Rust programming language, so I'm not well versed in yet.

I'm having trouble compiling Lemmy 0.18.1 with it, and I'm not quite able to figure out it out by myself yet.

Following is an excerpt from the build log:

I'm running Rust 1.71.0 on FreeBSD 13.2-RELEASE, if it helps.

Any help is appreciated.

Thanks in advance!

I suspect that somewhere in your dependency tree is a line of extern crate panic_unwind; which forces panic=unwind. Why is your build system forcing panic=abort for the html2md binary?

Hi @riking –

Thank you for the hint. It was coming from CARGO_PROFILE_RELEASE_PANIC="abort" environment variable which FreeBSD ports system defines when LTO feature is ON.

Thanks
