            Bug ID: 28019
           Summary: ld killed by OOM killer linking QtWebengine 5.15
           Product: binutils
           Version: 2.35.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: ld
          Assignee: unassigned at sourceware dot org

  Target Milestone: ---

Building Qt 5.15 with KDE's patches (https://invent.kde.org/qt/qt/qt5) on
Fedora 34 with binutils-2.35.1-41.fc34.x86_64, linking QtWebEngineCore gets
killed by the OOM killer. Build instructions are on the Qt wiki
(https://wiki.qt.io/Building_Qt_5_from_Git). It needs this small patch to build
with GCC 11:
