I'm porting an old application from Qt 5.3.2 to Qt 5.9.6 (yeah, I know, we're a
lot behind...). I'm running into an issue where code we had that was writing
out settings via the QSettings constructor that takes a file name doesn't work
anymore. I've attached a fairly minimal example that shows this.
What I've found so far:
- this code works perfectly on Windows using Qt 5.3.2 (mingw 4.8.2)
- this code works perfectly on a Mac using Qt 5.9.6 (clang)
- this code fails on Windows using Qt 5.9.6 (mingw 5.3.0)
Anyone have any ideas?

Hi, just tested your example program in MSVC 2017 Qt 5.12.1 and it fails
as well.
But a simple fix is just to make sure that the QFile file isn't open at
the same time as you write out the settings to it.
I.e. in your example program, it suffices to move that first
file.close(); up to just before the "// write out via QSettings" comment
line is, then it runs flawlessly.
But perhaps that's not possible to keep those writes separate in time in
your "real" app that your porting?
