--- Comment #13 from Victor Porton <porton at narod dot ru> --- It is a GCC bug rather than an Ahven bug, because the bug is triggered by `with Ada.Text_IO;` (and disappears if we remove this line from spawn-signals.adb) which should not influence semantics of the program, because the imported package is not used.
