A Flag added to compilation without being recorded in IDE files

Working with a fusa RTX safety compiler.

Compiling ,  .__i files shows the flags which can be sourced to the uvprojx file. 

Except for ONE flag that appears from nowhere : -fno-exceptions

I searched the entire project, there is no mention in any keil uvision files for that flag. How does he then being added ?



This is a major issue when trying to export the project , the flag will not show up as it is not in the uvproj file !!


Looking for explanation/ solution


thanks
