Arch Build failing

[duckunix]

x86_64, Arch fully up-to-date before running install. I get the following errors:

I've only seen this when building for Fedora so far (and since this build is only conduced on OBS I couldn't figure out what's wrong). It would be useful to have a stack trace.

Hi, same issue here. Test case of Debug build says this:

Oddly enough, on another computer the test case passes. In case the CPU matters: the computer where the test passes has an Intel i7-3610QM; the one where it fails has an AMD Ryzen 5 1600X.

Edit: running up-to-date ArchLinux too.

[Martchus]

It doesn't fail on any of my systems (which have various different CPUs) but I'll have a look at the functions the backtrace is pointing to. (I previously saw failures within my builds on OBS but couldn't debug them.)

[suiryc]

For information, the previous version (5.10.1) is ok: test case passes without crash. (but maybe the crash in 5.10.2 happens in a test that did not exist in 5.10.1)

[Martchus]

I pushed a commit which should fix this. The backtrace was very useful.

[suiryc]

It appears to be fixed indeed. Tried makepkg (AUR tool) to build from git sources: the test does now pass (and was still failing before the latest commit).

[suiryc]

No issue installing the latest 5.10.3-1 package on ArchLinux for me. Thank you for your tools, and the fix.

[Martchus]

Good. The crashes I've observed on OBS within the Fedora builds are gone as well. So I'm closing the issue.
