macOS 10.12.6
Newly installed vanilla Qt 5.1.0, installed from offline installer.
Using Qt version 5.10.1 in /usr/local/Qt5.10.1/5.10.1/clang_64/lib.
Description
The following code segfaults at exit.
#include <QGuiApplication> #include <QIcon> static QIcon foo; int main(int argc, char* argv[]) { QGuiApplication app(argc, argv); foo = QIcon(QString("bug.svg")); return 0; }
usually with a stack trace that looks like this
Thread 0 Crashed:: Dispatch queue: com.apple.main-thread

The symptoms seem identical to QTBUG-50829
If the test code is modified to use a png file then it exits cleanly with no crash, so I suspect it's a similar cause.
(With the svg file It will sometimes, instead, print "Pure virtual function called!Segmentation fault: 11" with nothing useful in the stack trace.)
