Subject: [Bug c++/105709] New: FORTIFY_SOURCE=3 (*** buffer overflow detected ***: terminated) on Qt
Date: Tue, 24 May 2022 00:07:49 +0000 [thread overview]
Message-ID: <bug-105709-4@http.gcc.gnu.org/bugzilla/> (raw)
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=105709
Bug ID: 105709
Summary: FORTIFY_SOURCE=3 (*** buffer overflow detected ***:
terminated) on Qt
Product: gcc
Version: 10.3.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: sam at gentoo dot org
CC: siddhesh at gcc dot gnu.org
Target Milestone: ---
Originally reported downstream in Gentoo at https://bugs.gentoo.org/847145.
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

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

make: *** [Makefile:71: sub-src-install_subtargets-ordered] Error 2
* ERROR: net-libs/accounts-qml-0.7-r1::gentoo failed (install phase):

```
Backtrace of the original failure:
```
Using host libthread_db library "/usr/lib64/libthread_db.so.1".
Core was generated by `/usr/lib64/qt5/bin/qmlplugindump -notrelocatable
Ubuntu.OnlineAccounts 0.1 .'.
Program terminated with signal SIGABRT, Aborted.
