Cherry,
Which fortran compiler do you use? Vasilii is right, it looks like you compiled BLACS using incorrect settings (you can see double underscores in the end of BLACS subroutine, and only one in rdiag). This second underscore comes from BLACS settings (unless you are using g77 compiler). You should always test your own compiled BLACS before using it (there is TESTING directory inside BLACS).
By the way, using agressive optimization like -O3 never helps numerical libraries, -O2 is more appropriate.

It doesn't help. I compiled everything with mpif77 -O3 (SIESTA, BLACS, and
