 @mitya57 looks like glibc in proposed may make qtwebengineprocess crash at start
 Is it again 32-bit specific, or happens on any platform?
 amd64 on my quick test
 I should also note that webengine FTBFS in the test archive rebuild with glibc 2.34 and GCC 11
 https://launchpad.net/ubuntu/+archive/test-rebuild-20210805-impish/+build/21921864
 as did 4 other Qt sources https://people.canonical.com/~doko/ftbfs-report/test-rebuild-20210805-impish-impish.html#kubuntu
 qtwayland and qtdeclarative are already fixed in git. I didn't upload because I waited until Debian freeze ends, will upload soon.
 Regarding qtwebkit error, I have no idea what to do about it:
 /usr/bin/ranlib: Failed to load plugin '/usr/bin/../lib/x86_64-linux-gnu/bfd-plugins/libdep.so', reason: /usr/bin/../lib/x86_64-linux-gnu/bfd-plugins/libdep.so: cannot open shared object file: Too many open files
 Regarding qtwebengine, https://code.qt.io/cgit/qt/qtwebengine-chromium.git/commit/?id=b498f4ce3f542882 should fix it, I will cherry-pick it
 @RikMills Can you provide more details about the glibc error?
 https://matterbridge.lubuntu.me/4a913317/file_3154.jpg
 things like that
 notpadqq also, but not a useful message
 also: https://bugs.launchpad.net/calibre/+bug/1939958
 i.e. calibre dev says that is due to qtwebengine not starting
 which is what made me start looking
 so far tested notepadqq, qutebrowser, falkon, konqueror
 all broken with just upgrading glibc
 other things are harder to test, as they only use webengine for certain things in the UI
 @mitya57 is that patch all there is to apply? I would like to see if the crashes still happen with a fixed build
 @RikMills Actually I discovered that the patch I mentioned is already included in 5.15.5. So I'm now cherry-picking part of https://github.com/abseil/abseil-cpp/commit/a9831f1cbf93fb18 instead.
 I can upload it to a PPA if you want to test.
 that would be great when you are ready :)
 I will re-use https://launchpad.net/~ci-train-ppa-service/+archive/4642/+packages where I tested a different qtwebengine fix for Hirsute
 great. thanks
 also breaks the dictionary and webbrowser applets from kdeplasma-addons
 Uploaded.
 Thanks
 Looks like a very similar fix for SIGSTKSZ is needed in one more place (breakpad). I will add it a bit later.
 opensuse people just pointed out: https://people.canonical.com/~ubuntu-archive/proposed-migration/update_excuses.html#glibc
[12:20] <fvogt> [14:18] <krop> the chromium package has this change https://chromium-review.googlesource.com/c/chromium/src/+/2936184
 https://matterbridge.lubuntu.me/1826b878/file_3155.jpg
[12:20] <RikMills> fvogt: cheers
[12:22] <mitya57> fvogt: Thank you! I will add that change too.
 @RikMills Uploaded second version to the PPA.
 https://bugs.launchpad.net/ubuntu/+source/qtwebengine-opensource-src/+bug/1939993
 Saw it, will close via changelog if you confirm that the fix works
 kool. I mostly did it to make sure we have a block-proposed tag on glibc for now
 Not that that will migrate any time soon.....
 It appears to be causing quite a bit of other breakage
 https://people.canonical.com/~ubuntu-archive/proposed-migration/update_excuses.html#glibc
 Yeah
 https://matterbridge.lubuntu.me/beeaa983/file_3157.jpg
 I think that confirms it is the sandboxing!
 Great, then 90% is that the fix will help.
