But then, if some source files have not been executed, some .da files remain empty making gcov aborts. The simple fix below simply does the same thing with empty .da file as if the file was not present. --- gcov.c.ori 2003-07-23 22:17:41.000000000 +0200 +++ gcov.c 2003-07-23 22:25:50.000000000 +0200 @@ -471,6 +471,18 @@ fnotice (stderr, "Could not open data file %s.\n", da_file_name); fnotice (stderr, "Assuming that all execution counts are zero.\n"); } + + /* Check for empty .da file.
