An example: program real*8 a(10000,10000) ! an 800MB array common /test/a end However on one SGI origin2000, MIPSpro Fortran 90 Version 7.3, the compiling fails. On another SGI origin2000, Ragnarok Compilers: Version 6.2, the compiling passes. It also passes on DEC Alpha with Digital f90 compiler. It seems that the SGI f90 compiler (version 7.3) puts the common block data to the stack segment instead of data segment. The error message is 'exceeds 268,435,455 bytes, the maximum storage size available' Any hints? Thanks.
