 Ihar Hrachyshka | * I asked in arm channel for someone to test if Firefox crashes on Linux arm too since I don't have a desktop machine myself. There was no reply.
Looking at the patch in llvm I do not think it's specific to Darwin but I can't prove.
And of course Firefox is the app that we know is broken but it's maybe / probably not the only one (though probably also relatively rare). | 02:58:35 |

 K900 | @Yureka (she/her) so are we sure the Firefox crashes are Mesa and not the LLVM miscompilations? | 07:42:38 |
 Vladimír Čunát | Yes, most of the combinations are in cache.nixos.org at this point. | 07:47:43 |
| Vladimír Čunát | (I looked at 2 pythons * 4 platforms) | 07:48:02 |
| Vladimír Čunát | * (I looked at 2 pythons * 4 platforms via nix-env -qas) | 07:48:10 |
| Vladimír Čunát | And it doesn't seem urgent. | 07:49:20 |
| Vladimír Čunát | Sounds suitable for backport, i.e. just delayed a bit. | 07:49:59 |
| Vladimír Čunát | I switched the PR according to that. | 07:50:30 |
| Vladimír Čunát | * (6/8; I looked at 2 pythons * 4 platforms via nix-env -qas) | 07:52:35 |
 Yureka (she/her) | Yes | 08:18:55 |
| Yureka (she/her) | Because I reproduced a crash with llvm 19 firefoz | 08:19:11 |
| Yureka (she/her) | * | 08:19:16 |
| K900 | Fun | 08:19:30 |
| Yureka (she/her) | But it has been running smoothly since I downgraded mesa | 08:19:33 |
| K900 | Do you have a backtrace? | 08:19:34 |
| Yureka (she/her) | I don't know how to get backtraces from the firefox crash reports | 08:19:52 |
| K900 | Do you have a crash ID then? | 08:20:09 |
| Yureka (she/her) | How would I get the crash id? | 08:21:30 |
| K900 | about:crashes | 08:21:51 |
| Vladimír Čunát | Uh, the fast influx of rebuilds to master keeps going on 😥 | 08:54:17 |
| Vladimír Čunát | I mean, infra can handle it, but it will slow down staging* cycles... | 08:54:55 |
| Yureka (she/her) | Report ID Date Submitted

| K900 | Uh oh no debug info | 09:00:11 |
 dramforever | are those possibly in coredumpctl | 09:00:32 |
| K900 | Doubt | 09:00:41 |
| K900 | They should be caught before that | 09:00:44 |
| K900 | With breakpad | 09:00:45 |
