https://gcc.gnu.org/bugzilla/show_bug.cgi?id=93764 --- Comment #3 from Martin Liška --- I bet the generated code is wrong. But it's caused by LZO violation of the strict aliasing. Please open a bug for lzo.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=93764 --- Comment #2 from Tomasz Kłoczko --- If gcc produces correctly working code I think that it would be better to just disable that single test if code with aliasing is faster.
