[ccache] Bug in ccache 2.4

[Ioannis Kappas]

Hi,
 
      the following may fail on some systems due to a const char pointer being freed in failed() while still being referenced by ARGS
 
$ touch test.i
$ ccache cc -anything -c test.i
cc: Ð(¸V@°V@°V@: No such file or directory
cc: No input files
 
here is a patch that fixes the problem:
 
diff -rc ccache-2.4.original/ccache.c ccache-2.4/ccache.c

!   path_stdout = input_file;

     stats_update(STATS_ERROR);
