[12:24] santa_: It looks like the kio 5.113.0 in noble-proposed is causing Dolphin to always crash on start with "*** buffer overflow detected ***: terminated". That didn't happen for the same version of the package in staging-frameworks. [12:28] It looks like it might only occur when browsing to a directory with a symlink, but my home directory has several of those, which results in crashing on start. [12:52] It looks like the toolchain might have started setting "-D_FORTIFY_SOURCE=2" by default. I bet that has something to do with it. [13:03] that would be a change in dpkg [13:04] https://launchpad.net/ubuntu/+source/dpkg/1.22.1ubuntu4 [13:04] I think [13:09] Ah, OK. I just guessed it was in the toolchain, sorry. I noticed it because a package I build started FTBFSing with an error about _FORTIFY_SOURCE being redefined. [13:13] You're definitely right though, the PPA build was done with _FORTIFY_SOURCE=2 and the archive build with _FORTIFY_SOURCE=3. [13:16] So what's the proper way to deal with this? [13:19] maybe force =2 in debian/rules? [13:19] not sure [13:19] assuming this is the cause [13:21] I was going to do some empirical testing and find out. I'm not quite sure how to set _FORTIFY_SOURCE in debian/rules though. (I'm just an amateur at this whole debian packaging thing.) [13:24] Hi all [13:25] It looks like I could turn off hardening altogether by using export DEB_BUILD_MAINT_OPTIONS = hardening=+all,-fortify, but that's not what I want. [13:29] maybe something like https://salsa.debian.org/postfix-team/postfix-dev/-/commit/d1d1217d8560ae6ffe0ed670610d267bb9d3737d [13:29] -ubottu:#kubuntu-devel- Commit d1d1217 in postfix-team/postfix-dev "Bump _FORTIFY_SOURCE to level 3" [13:29] * RikMills shrugs [13:30] That should do the trick, thanks! (I wasn't aware that DEB_CPPFLAGS_MAINT_APPEND existed,) [13:37] Yes, that works. I rebuilt kio with "export DEB_CPPFLAGS_MAINT_APPEND = -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=2" in debian/rules and Dolphin no longer crashes on start. Thanks for the help!
