This gdb_exit, gdb_start, gdb_reinitialize_dir sequence right after clean_restart tells me that perhaps one of them is redundant.

I think the "compile_unit" line is not properly indented.

Abid> clean_restart tells me that perhaps one of them is redundant.

Good catch.
Given the rest of the test I think the clean_restart is not needed.
