Backtrace

@francesco-gaglione Why did you say this is "random"? Does the build sometimes succeed?

[francesco-gaglione]

@saethlin nope, I mean it generate this error on a random dependecy build. Just a note if could help... I tryed to clean everything, cache, build and everything that I can clear, the build passes, than build again, not pass... I repeted the clean but it do not pass, it is random, I can say it work onece on 50 attempt. Just last note, yesterday rust-analyzer causes some crash because It ate all 64gb of ram on my pc. Today I did a dependency update and it no longer eats all the ram but the problem remains that it does not build

[saethlin]

So it crashes on a different dependency each time?

Or do you always get

error: could not compile wgpu-hal (lib)

[francesco-gaglione]

@saethlin yes correct. It crash on a different deps each time.

[francesco-gaglione]

I think u can easly reproduce it, clone the repo and run just run if u are Lucky and work, run it again and it will never work again.
Ah very important update, I tried to run the build a lot of times, 20 times more or less and it worked. I don't want to say wrong things, but it's a bit like a buffer, it fills the buffer and breaks, you start again and start from where it stopped until it fills up again. So if you try endlessly sooner or later it will end. In fact if I try to do a flatpak build it doesn't work even after 50 times because it always starts from 0

[saethlin]

I've done cargo clean then just run a handful of times and no segfaults. just run pulls up an interactive app which I don't want to figure out how to kill from a script, so I'm just going to cargo clean then cargo build --release in a script a hundred times.

But at this point I do not think I am going to find a crash. Since you're getting different sporadic and different segfaults, I suspect this is defective hardware, not a compiler bug. You can find all the other issues we root-caused to defective hardware by searching for the label: https://github.com/rust-lang/rust/issues?q=is%3Aissue%20state%3Aclosed%20label%3AC-defective-hardware

What CPU model do you have?
