When you compile C++ programs, you should invoke GCC as @command{g++}
instead. @xref{Invoking G++,,Compiling C++ Programs},

-and @code{g++} when compiling C++ programs.

@cindex options, grouping
programs depends, for example, on length of temporary file names or
memory space randomization (that may affect hash-table collision rate).
Such non-reproducible part of programs may be annotated by
-@code{no_instrument_function} function attribute. @code{gcov-dump} with
+@code{no_instrument_function} function attribute. @command{gcov-dump} with
@option{-l} can be used to dump gathered data and verify that they are
indeed reproducible.
