Description
- Have a simple program running QSvgRenderer::render
:
#include <QApplication> #include <QImage> #include <QPainter> #include <QString> #include <QSvgRenderer> int main(int argc, char *argv[]) { QApplication a(argc, argv); static QImage image(200, 200, QImage::Format_RGB32); static QPainter painter(&image); QString filename(argv[1]); QSvgRenderer renderer(filename); renderer.render(&painter); return 0; }
- Build it on Qt 5.12.3, built with -sanitize address.
In case it's important, mine also was a release build. - Run the program passing the attached input file as parameter: <svg><text></text></svg>
The program reports a leak:Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway. ================================================================= ==10779==ERROR: LeakSanitizer: detected memory leaks Direct leak of 256 byte(s) in 1 object(s) allocated from: #0 0x7f1a8f1e0b50 in __interceptor_malloc (/usr/lib/x86_64-linux-gnu/libasan.so.4+0xdeb50) #1 0x7f1a81a7e8ed (/usr/lib/x86_64-linux-gnu/libfontconfig.so.1+0x1d8ed) Indirect leak of 32 byte(s) in 1 object(s) allocated from: #0 0x7f1a8f1e0d38 in __interceptor_calloc (/usr/lib/x86_64-linux-gnu/libasan.so.4+0xded38) #1 0x7f1a81a7efd8 (/usr/lib/x86_64-linux-gnu/libfontconfig.so.1+0x1dfd8) SUMMARY: AddressSanitizer: 288 byte(s) leaked in 2 allocation(s).
