Bug ID: 374046
Summary: GCC address sanitizer-enabled apps crash with QtCurve
Product: QtCurve
Version: unspecified
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: qt5
Assignee: yyc1...@gmail.com
Reporter: eugene.shalygin+bugzilla....@gmail.com
CC: h...@kde.org
Target Milestone: ---
When an application is compiled with -fsanitize=address, it crashes on startup.
Below is a part of stacktrace. Unfortunately, the qtcurve part is not decoded.
I'm on Gentoo, qtcurve installed with debug CXXFLAGS, splitdebug and
installsources features enabled, but no good stacktrace :(
