C++ 2 Eclipse Based IDEs, 1 catches exceptions, the other doesn't - c++

Question

I'm a little stuck at the moment.
I have been working on a C++ project lately but i'm having trouble with exceptions.
The target is an STM32.
I set up 2 projects using STs Cube MX Code Generator.
The code executed is
try
{
throw 1;
}
catch(const int& ex)
{
configASSERT(0);
}
My used IDE (SW4STM32, eclipse based, g++) fails to catch the exception. I'm always running into the termination handler. The other IDE (atolic true studio, eclipse based, g++) catches the exception.
Therefore it's not a target problem but an IDE problem. I already did remove the fno-exceptions from the g++ compiler and the linker options. But still no luck.
Do you have any others ideas on where to look?
Thx :)

Now as you can see, there is no fnoexceptions active. Therefore I'd expect to receive exceptions. :(
SW4STM32 uses Eclipse Platform 4.6.3 Eclipse CDT 9.2.1
Attolic uses Eclipse Platform 4.6.1, Eclipse CDT 9.1.0
So the eclipse base versions are pretty similar.
Do you have any other ideas?
