error when compiling a very simple code with a relative big array

[Feng_Feng]

Everyone:

Following code can be compiled without any problem on one old Alitx machine 32 CPUs and 256GB; however got errors as below on a new SGI Altix machine with 384CPUs and 1.6TGB.

Thanks.

Use

real :: test(:,:,:)
...
allocate(test(200000,30000,10))

The way your program is written when compiled for Intel64 or IA32 the array test will be placed in the static data block (.bss). The linker has a restriction of 2GB for any "segment" (static data, code, etc...). Therfore use allocatable arrays (or heap arrays).
