 It looks like redefining `_FORTIFY_SOURCE` in Qt broke veyon:

 Do you mean the qtbase upload, or the settings now in dpkg and gcc-13 that set `_FORTIFY_SOURCE`=3 as the new default? (re @mitya57: It looks like redefining _FORTIFY_SOURCE in Qt broke veyon:
 https://launchpadlibrarian.net/706208072/buildlog_ubuntu-noble-amd64.veyon_4.7.5+repack1-1build3_BUILDING.txt.gz)
 I mean the qtbase upload. That's where =2 comes from, I guess.
 :(
 Reverting that will a) cause many things to crash on start, and b) qtbase would never migrate as multiple autopkgtest against it would fail
 I guess the best thing would be an upstream fix for qtbase to not crash things if built with =3
 I have no clue on that though
 Maybe we should find where qtbase stores information that it was built with =2 and delete it?
 If that is a thing, then yeah
 ```
 $ reverse-depends src:veyon
 No reverse dependencies found```
 so not a disaster if we have to push that out of the release pocket for a bit
 Ok. Let's see if some other package breaks with the same symptoms.
 yeah
 FYI, I also saw that if you don't build qtbase with =2, then qtlocation FTBFS
 qtlocation was NCR for the icu transition and failed with the original =3 qtbase
 then built ok on retry after qtbase was fixed
 Ack
 @mitya57 also if you want to trying building some things with different options, I have the ppa:

 Ack. In fact I don't have much time today, maybe I'll play with it later.
 Of course. Thanks as always for what you have time for :D
