The only flag I could remove is -mshstk, and without that tests just take longer to fail:

It's worth noting that this started to happen after upgrading to gcc-14.

Same thing with -march=x86-64-v4 and with -march=znver4 and no LTO.
Comment 3 Sam James archtester Gentoo Infrastructure gentoo-dev Security 2024-11-25 15:30:50 UTC
Excellent, thanks. Same version passed before?

Clang?
Comment 5 Paolo Pedroni 2024-11-25 15:41:18 UTC
(In reply to Sam James from comment #3)
> Excellent, thanks. Same version passed before?

Yes, it did. Another possible difference is that the last time it worked, it was built against kde-frameworks-6.6.0, while now it is against kde-frameworks-6.7.0.

> Clang?

I use to build qt with clang, ever since we had qt6 in tree: never had any issue with it.
Comment 6 Sam James archtester Gentoo Infrastructure gentoo-dev Security 2024-11-25 15:44:27 UTC
But then it's not really obvious if it's a GCC problem or a Clang one. I can't really do much with this as-is.

It used to work in the same conditions. Only difference is GCC and kde-frameworks version.

I could revert to previous kde-frameworks and try again, but it's going to take a while. Do you think it may be worth to try?
Comment 8 Sam James archtester Gentoo Infrastructure gentoo-dev Security 2024-11-25 15:57:51 UTC
I understand, but I need to be able to reproduce it, and having a mix of things to try emulate locally isn't great. Especially as Qt has often had UB in the past, so it being built with Clang could be relevant.

It would be more useful, if possible, to build KF and Qt with the same compiler and verify it happens, rather than downgrade.

I will try tomorrow.
Comment 10 Kostadin Shishmanov 2024-11-26 23:04:42 UTC
FWIW, these also segfault for me when I build kde-apps/kate-lib with portage, but if I try to build it "locally" in my home directory, the whole test suite passes with no failures.

That would mean either:
a) sandbox;
b) some other environment variable
usually.

If you run it in a terminal after sourcing the environment file in a subshell, does it fail?
Comment 12 Sam James archtester Gentoo Infrastructure gentoo-dev Security 2024-11-27 00:39:19 UTC
We discussed it on IRC.
