Qt Creator can't stop at breakpoints

Hi!
I'm new on Qt Creator and i'm having an issue with it.
Today i've tried to create a non-Qt c++ project and i've discovered breakpoints doesn't work.
I tried to create different project types and the only one which stops at breakpoints is "Qt application project"
I tried to update gdb because i saw on the internet that wolud be caused by an old gdb version which has a bug, but it didn't work.
I'm currently running Debian OS with g++ 6.2.1

Can anyone help me?
