Description Mamoru TASAKA 2022-03-25 02:14:25 UTC 
Description of problem:
With binutils-2.38-6.fc37, trying to link against /usr/lib64/libQt5WebEngineCore.so.5.15.8 (from qt5-qtwebengine-5.15.8-5.fc37.x86_64) causes linkage error like:

/usr/bin/ld: /usr/lib64/libQt5WebEngineCore.so: undefined reference to `std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >::_M_create(unsigned long&, unsigned long)@GLIBCXX_3.4.21'

or so.

Tried with
tellico-3.4.4-2.fc37 https://koji.fedoraproject.org/koji/taskinfo?taskID=84590679
ghostwriter-2.1.2-1.fc37 https://koji.fedoraproject.org/koji/taskinfo?taskID=84622587 

Version-Release number of selected component (if applicable):
binutils-2.38-6.fc37
qt5-qtwebengine-5.15.8-5.fc37.x86_64
tellico-3.4.4-2.fc37
ghostwriter-2.1.2-1.fc37

How reproducible:
100%

Steps to Reproduce:
1. mockbuild rawhide tellico or ghostwriter
2.
3.

Actual results:
Observer linkage error

Expected results:
linkage succeeds

Additional info:
For both cases just downloading binutils, binutils-gold to 2.37-24.fc36.x86_64 makes linkage succeed, so I suspect this is due to binutils change.
Comment 1 Mamoru TASAKA 2022-03-25 02:47:41 UTC 
Note that LTO is related here. Disabling LTO makes linking succeed with binutils-2.38-6.fc37
Comment 2 Nick Clifton 2022-03-30 11:27:49 UTC 
Fortunately this bug has already been reported and fixed upstream (PR 28879), so I will backport the patch to rawhide.
Comment 3 Nick Clifton 2022-03-30 12:30:26 UTC 
Fixed in binutils-2.38-7.fc37.
Comment 4 Ben Beasley 2022-03-30 13:56:23 UTC 
I did a scratch build using your side tag and confirmed luminance-hdr builds with LTO enabled again: https://koji.fedoraproject.org/koji/taskinfo?taskID=84938083
Comment 5 Mamoru TASAKA 2022-04-02 14:12:05 UTC 
binutils-2.38-7.fc37 is now in f37 buildroot.
