I would recommend setting the /Zo option for enhanced debugging
information
in your application release build. ( is default in vs 2017).
Alternatively you can change disable your optimisation in release build
with /Od.
you CANNOT use a qt application debug build with Qt realease dlls,
because that will crash , due to using a mix of release and debug
c-runtime dlls, which have different memory allocators. The debug c
runtime will allocate extra bytes for debugging purposes, which the
release allocator does not know of. So it crashes if you allocate with
the debug allocator and delete with the release allocator or vice versa.

Subject: [Interest] Use Qt release DLLs while debugging application
This must be an FAQ, but can I use the Qt release mode DLLs while
running my application compiled for debug? (In Visual Studio 2015, Qt
5.8).
I looked through the mkspecs and it doesn't seem possible. The
qtPlatformTargetSuffix function defined in qt_functions.prf always adds
the d suffix when compiling for debug.
I ask because I'm not debugging Qt, and the XML parsing in Qt5Xml seems
to be horrendously slow in debug mode. It's using 45% of my total CPU
time, versus 11% in release mode. I'm not actively debugging anything
remotely related to XML but this is killing debug time for me.
