    Description

      When trying to continue execution after having placed a breakpoint to an invalid memory location, the debugger doesn't advance the program and doesn't give any feedback or error message to the user (see video).

      This happens on Windows on a program compiled with MSVC 2022 and using cdb as the debugger. Trying the same example on linux with gcc and gdb results in a "SIGILL illegal instruction" or "SIGBUS bus error" error message.
