One should find the fix, I do not see it obvious which one it is.

gdb_run_cmd produces output which is not caught anywhere here.  This will
result in testcase races.

BTW runto expects a function name, not file:line notation.

This is why the pair
	gdb_breakpoint [gdb_get_line_number "break-here"]
	gdb_continue_to_breakpoint "break-here" ".* break-here .*"

is popular.
