With the -O2 modifier it works, but without it, it produces 

~# ./a.out 
 -0.99440605160172935  -0.99440605160172935

Well, running the code snippet with all GCC releases I have (and all
optimizations levels), I can see:

$ gfortran pr78062.f -O2
$ ./a.out
 -0.10562482917315752  -0.99440605160172935 

May I ask you what's your target and version of GCC?
