--- Comment #10 from Stephen Kelly <steve...@gmail.com> ---
Hi am trying to run valgrind on OSX and I think I am hitting the same problem.
I have this embarrassingly simple Qt 5 program:
cat main.cpp
#include <QCoreApplication>
int main(int argc, char** argv)
{
QCoreApplication app(argc, argv);
return app.exec();
}
and I build it with Qt 5.7 alpha which I built from source.
When I run valgrind on it, I get this:
valgrind qt.app/Contents/MacOS/qt

HANG!!!!!!!
So, valgrind just hangs.
This is before and after the patch in comment 9. That is, I patched valgrind
and instructed homebrew to build from source.
Is there some other step to make valgrind usable on OSX?
