[Comment 4 Arniii 2025-01-14 17:49:30 UTC]

reproducible with media-libs/openh264-2.5.0

[Comment 5 Joonas Niilola 2025-01-14 18:17:42 UTC]

The tests works for me at least on amd64. Could be ggdb (didn't try that), could be graphite, could be something else broken if your whole system is compiled with those settings. There's nothing relevant in upstream issues either. So at least it doesn't seem like a common issue.

[Comment 6 Sam James 2025-01-14 18:19:54 UTC]

As I've asked before, please make an effort to reduce what's causing it.

[Comment 7 Arniii 2025-02-28 10:23:11 UTC]

reproducible with version 2.6.0

I'll try reduce it.

[Comment 8 Arniii 2025-02-28 12:14:50 UTC]

1. not reproducible wtihout LTO and Graphite
2. not reproducible without Graphite.

It's graphite issue.
