Not working fine on macOS

[50U10FCA7]

Inventory stops collecting anything on MacOS in some cases. Think it's because of fn pointers inside plugin, but not sure.

Here's MRE (see GitHub actions):

Expected output: https://github.com/50U10FCA7/inventory_issue_test/runs/8248537681?check_suite_focus=true#step:4:26
Actual output on MacOS: https://github.com/50U10FCA7/inventory_issue_test/runs/8248538107?check_suite_focus=true#step:4:26

This works for me with:

[profile.dev]
incremental = false

[profile.release]
codegen-units = 1

Still unclear why this problem appears, but linkme crate has the same issue: https://github.com/50U10FCA7/inventory_issue_test/runs/8305029222?check_suite_focus=true#step:4:24

Looks like problem with linkage on macOS.

It would be an appropriate use of panic to include static assertions that check the CARGO_PROFILE__CODEGEN_UNITS env variable as a way of making sure that should inventory be a dependency this is not overlooked.

[profile.dev]
incremental = false

[profile.release]
codegen-units = 1

This is definitely not working for me. Only some instances of inventory::submit! are being picked up even if I blow away the target directory.

Been trying to figure this out as well, but I haven't ever gotten it to report anything but empty results so far. Also, the codegen units fix doesn't seem to work in my case either.

I saw this problem for 0.3 and the following did fix it for me, at least for tests.

[profile.dev]
incremental = false

This is an upstream issue in rustc: rust-lang/rust#133491
