pineapple-pictures v0.8.0 fails to build on i386

[sudipm-mukherjee]

I updated pineapple-pictures in Debian today to v0.8.0 but it fails to build for i386. The previous v0.7.4 did not have the build failure.

The build log of v0.8.0 for i386 can be seen at https://buildd.debian.org/status/fetch.php?pkg=pineapple-pictures&arch=i386&ver=0.8.0-1&stamp=1722081327&raw=0

I will be happy to give any extra log or test any patch if needed.

I guess it's very likely a Qt6 issue or SSE2 support issue? Since according to the log that you provided, it's unlikely related to Pineapple Pictures itself.

Yeah, seems like you are correct. I ran a pipeline with 0.7.4 on i386 and that now fails. So, something else has changed. I will look more into it. Thanks a lot for the quick reply and support.

Closing this issue as this has been seen on other packages also and https://codereview.qt-project.org/c/qt/qtbase/+/579205 has been opened.
