Installed GDB using home-brew on macOS Sierra (10.12.5) and code signed it. GDB works with FPC compiled executable from the terminal. But in IntelliJ (both community and ultimate) the Console output for the debugger shows the following and does not run.
Setting new breakpoints once in debug mode adds more "undefined commands" messages.
Other than that... fantastic plugin so far.
