Qt Creator debugging code in MSVC and CDB

range36rus

I use Qt 5.12.3, Qt Creator 4.9.1, MSVC 2017 x64 and debugger CDB. I'm doing a step-by-step debugging of this code:

try
{
   int a(458);
   throw a;
}
catch(int& a)
{
     qDebug() << a;
}

An exception occurs and it is displayed:

But I don't hit the catch block, the app just stops. How to fix this problem? Thanks.

P.S.:
I saw this message and it does not work:

I checked all the debuggers from the Win 10 SDK, Win 8.1 SDK, and even the Win 7 SDK!
X86 and x64 versions.I can't get into the catch block in all cases, the debugger have an error and just stops. Has somebody ever had such a problem?
