Rust doesn't stop you to divide by 0, I think... so crashes are still possible.


That's true about the (mostly) safe crashes as I've seen it described by the creator. Though, Rust isn't about avoiding crashes. Rust is mainly about avoiding common security and usage pitfalls in C++ while providing built in concurrency.

Rust being a New Language, unlike Gecko which is pretty solid


Its not really about the language being new(its based on C++ after all). Its just the nature of bleeding edge software. Crashes WILL happen. They happened before Rust, they will happen after Rust.

Anyone else have issues on this page (make sure you get the HTML5 player)? The green marker repeatedly disappears while playing. Disabling hardware acceleration seems to help.

Exactly this. Any language can crash and some of the crashes we have seen recently are intentionally instigated wile trying to debug and resolve some underlying issues.

I played the first three lines and didn't see any gaps in the display of the green marker. I tried with Chromium and the page display seemed to be the same.

(Using a reasonably fast computer with plenty of memory running Linux.)

Just a heads up, looks like updates are going to be frozen on the first 20170718 nightly until the Stylo issues are resolved.

Nice! That's fantastic news. Hopefully this means the builds will not be frozen for too long then.

The list of fixes includes the fix for the crashes people were hitting the last few days (due to an assertion being enabled last week) and the startup crash people started hitting in the respin build. Auto-update is disabled but should be reenabled soon.

This thread is closed, please use the next one.
