Description
Originally reported in Gentoo. Reported to GCC where it was explained that `qt_readlink` is to blame.
Noticed when building net-libs/accounts-qml (https://accounts-sso.gitlab.io/).
It crashed on calling qmake (part of qtcore) which was calling /usr/lib64/qt5/bin/qmlplugindump (part of qtdeclarative):
make[1]: Entering directory '/var/tmp/portage/net-libs/accounts-qml-0.7-r1/work/accounts-qml-module-VERSION_0.7/src' export LD_PRELOAD=Ubuntu/OnlineAccounts/libAccounts.so; /usr/lib64/qt5/bin/qmlplugindump -notrelocatable Ubuntu.OnlineAccounts 0.1 . > Ubuntu/OnlineAccounts/plugin.qmltypes /usr/lib64/qt5/bin/qmake -install qinstall /var/tmp/portage/net-libs/accounts-qml-0.7-r1/work/accounts-qml-module-VERSION_0.7/src/Ubuntu/OnlineAccounts/qmldir /var/tmp/portage/net-libs/accounts-qml-0.7-r1/image/usr/lib64/qt5/qml/Ubuntu/OnlineAccounts/qmldir /usr/lib64/qt5/bin/qmake -install qinstall -exe Ubuntu/OnlineAccounts/libAccounts.so /var/tmp/portage/net-libs/accounts-qml-0.7-r1/image/usr/lib64/qt5/qml/Ubuntu/OnlineAccounts/libAccounts.so *** buffer overflow detected ***: terminated make[1]: *** [Makefile:818: Ubuntu/OnlineAccounts/plugin.qmltypes] Aborted (core dumped) make[1]: *** Deleting file 'Ubuntu/OnlineAccounts/plugin.qmltypes' make[1]: Leaving directory '/var/tmp/portage/net-libs/accounts-qml-0.7-r1/work/accounts-qml-module-VERSION_0.7/src' make: *** [Makefile:71: sub-src-install_subtargets-ordered] Error 2 * ERROR: net-libs/accounts-qml-0.7-r1::gentoo failed (install phase): * emake failed
