Describe the bug

libsForQt514.qt5.qtwebengine currently fails to build locally and on hydra.
Build log on hydra

The interessting line seems to be:

/nix/store/m2vh2ny7bqpwij1gpmvl5gxj7y4dgr4f-binutils-2.38/bin/ld: /nix/store/ggj5c9a57qs8i83rxwv34hiz7jgm8hml-x265-3.5/lib/libx265.so.199: undefined reference to `std::__throw_bad_array_new_length()@GLIBCXX_3.4.29'
collect2: error: ld returned 1 exit status

The last successful build on hydra was linked to e111881. After that it seems to fail (starting with ba88a5a)

Bisecting takes forever. I would hazard a guess that it has to do with 95af224 and PR #168737 which broke some other packages as well.

EDIT:

# git bisect --first-parent
95af2245a32f8e1310ad4e3bf50b76d86ddbbc0a is the first bad commit
commit 95af2245a32f8e1310ad4e3bf50b76d86ddbbc0a
Merge: 212dde2609b 70d726c2a51
Author: Martin Weinelt <mweinelt@users.noreply.github.com>
Date:   Sun Apr 17 20:38:16 2022 +0200

EDIT2:
The error seems to stem from the c++ upgrade. The error message is referenced e.g. here JuliaLang/julia#40703.

Steps To Reproduce

Steps to reproduce the behavior:

  1. checkout nixpkgs master
  2. nix-build -A libsForQt514.qt5.qtwebengine .

Expected behavior

qt5: use 1t5.15 LTS for certain packages
cc4300e 
use qt5.15 LTS instead of 5.14 for packages currently
not building due to broken qtwebengine 5.14
(see NixOS#169996)

packages were checked on hydra and if broken, tried to build
with qt 5.15. If this succeeded, they were upgraded here.

It's most likely due to mixing gcc versions, as that's not 100% compatible in C++. qt514 (and qt512) get overridden to gcc10, whereas the default is gcc11. (For x86_64-linux; some others have other combinations.)
