• bcruey July 10, 2009 2:12 PM PDT    Maximum size for arrays being passed to a subroutine?? I have .f90 code that compiled and worked wayback when when I wrote it two years ago. I made some adjustments to the code but only cosmetic adjustments. I have since moved to a new computer with a different ifort compiler and it still works as long as I keep my arrays below 136X136. I compiled the program with a traceback and it points to a line in my code where I am calling one of my subroutines. The error code that I get is: severe (170): Program Exception - Stack Overflow Is there a maximum size for arrays that are being passed to a subroutine for Intel Visual Fortran 10.0? Do you have any other suggestions for what the issue might be? Steve Lionel (Intel) July 10, 2009 2:25 PM PDT Rate   #1 Re: Maximum size for arrays being passed to a subroutine?? There is no maximum size, but you have not said what the error is.  Is it "stack overflow" by any chance?  If so, try adding the option /heap-arrays (if you're using Visual Studio, type this in under Command Line > Additional Options.)

Quoting - Steve Lionel (Intel) There is no maximum size, but you have not said what the error is.  Is it "stack overflow" by any chance?  If so, try adding the option /heap-arrays (if you're using Visual Studio, type this in under Command Line > Additional Options.) I tried typing in "/heap-arrays"  from the intel Fortran Compiler for applications running on IA-32 command prompt. I got a message back saying that "/heap-arrays" is not an internal or external command. Not sure what I am doing wrong. Also these are Allocatable arrays. does that matter?

Are you building from the command line?  If so, then add /heap-arrays as an option to the "ifort" command.  No, it does not matter if the arrays are allocatable.  Is the error a stack overflow?  Can you show me the declaration of the subroutine or function you're calling (include declarations of all its arguments).
