fixed after cargo clean

from rust.

It's great that you managed to get your own workflow going by running cargo clean, but that papers over the problem. Crashes like this are not acceptable compiler behavior. I added this assertion in order to more clearly detect a bug if there was one, and clearly there is.

this panic happens after I fix an out-of-disk problem

from rust.

Ooooo I thought I fixed all of the out-of-disk problems in 1.77. I'll take a look again.

Ah I see you edited your message. What do you mean by "fix" here? Did you run out of disk during a build, then free up some space, then try to compile again and get this crash?

IIRC, this is the case

I'm working on a proxmox virtual machine
I notice proxmox's io-error (a yellow symbol) when I was using rust-analyzer in vscode,
then cleanup disk, with a lot of reboots
then compile, then panic

from rust.

I've just hit the same assertion after recompiling after a power failure.

I think we may need to call fsync / File::sync_all on the dep-graph.part.bin file before renaming it to dep-graph.bin, otherwise data might get lost.
