[Safari ?] Hangs randomly
Basically the title, when I try to use vim or just the terminal, the website hangs, the only way to fix it is reloading. js console shows a debug message of the format Fault addr cb8bb1a4, ip 556ece35, tid 4 followed by Fault from Inode 28281.
| Tool | Version |
|---|---|
| Safari | 15.4 (16613.1.17.1.13, 16613) |
| Macos | Big Sur 11.6.2 |
| Model | M1 Macbook Air 2020 |
Could you possibly run the same experiment either with Firefox (non-Incognito) and/or Chrome/Chromium (on the same device)?
I cannot, the computer has a whitelist of executables its allowed to run, and the only allowed browser is Safari. I doubt that those execute restrictions are the cause of the errors though.
I believe the problem here is that Safari 15.4 had a couple of stubble WebAssembly bugs (eg https://bugs.webkit.org/show_bug.cgi?id=237180) that you are most probably hitting against.
I did run some test on a IPhone with 15.6, and WebVM seems to work as expected.
Would it be possible for you to give it a try from a different machine and / or have your browser updated?
Nope, last test was run on 16.0, but i retested it anyways and it still hangs, this time while running a compilation using gcc, not vim.
Although we could never reproduce it locally we have fixed many bugs over the last few months. Can this problem still be reproduced?
Can't seem to reproduce any hanging on Safari 16.1 (18614.2.9.1.12), macOS 13.0 (22A380), M1 Macbook Air 2020.
vim:
gcc took a few minutes to cold start, but worked:
(Not sure what's going on with the user and sys time results there, but I'd imagine that's unrelated to this issue?)

The data structure is simply not populated and then mis-printed by user space, it is not a problem.
Closing this issue, it's likely that whatever problem was there originally has been fixed in the meantime
