GHDL recipe: debugging assertion warnings

This method doesn't work with ghdl-mcode.

  1. Build your simulation with debug infos (ie. add -g flag to the ghdl build)
  2. Open the generated executable in a debugger
  3. Add a breakpoint on the __ghdl_fatal function (in gdb b __ghdl_fatal)
  4. Run the program with --assert-level=warning as its argument (in gdb run --assert-level=warning)
  5. Use the debugger backtrace functionality (in gdb bt) to resolve the origin of the issue
