why is std::terminate not called when throwing in my destructor

I'm trying to "see" the call to std::terminate() when throwing from a destructor with the following code:

#include <stdexcept>

struct boom {
     ~boom() {
        throw std::logic_error("something went wrong");
     }
};

int main() {
     boom();
}

compiled with g++ and run the code:

# ./a.out
terminate called after throwing an instance of 'std::logic_error'
  what():  something went wrong
Aborted (core dumped)

so far so good, seems to work as expected (call terminate()). But when trying to break on terminate in gdb, the function does not get hit and the backtrace shows only abort:

(gdb) b std::terminate
Breakpoint 2 at 0x7f60a3772240 (2 locations)
(gdb) r
Starting program: a.out
terminate called after throwing an instance of 'std::logic_error'
  what():  something went wrong

Program received signal SIGABRT, Aborted.

This behavior is puzzling me somehow, is there something I am missing?

EDIT:

same test using clang++ and the std::terminate breakpoint is hit:
