Intel Fortran on Visual Studio 2013 64 bit debugging

I'm using Intel Visual Fortran Composer XE 2013 SP1 Update 3 and debugging in Visual Studio 2013 Update 2's IDE with this simple program:

program Console1

implicit none

! Variables
integer(4) testInt
! Body of Console1
print *, 'Hello World'
testInt = 7
end program Console1

When the EXE for this program is compiled with the "IA 32" (the Win32 platform) ifort compiler, the debugging works as expected. The watch on testInt changes from a random value to 7.

But, when I use the "Intel (R) 64" (the x64 platform) compiler by setting the project to the x64 platform, the debugger will stop at correct break points. But the watch on testInt reports "Undefined address" instead of 7.

What's going on here? How can I enable correct debugging for 64 bit Fortran compilations?

Solution

  • This problem has been escalated to Intel development. In the meantime, I suggest uninstalling Update 2 to VS2013, which you can do through Programs and Features > View Installed Updates. Once that is done, x64 debugging of Fortran programs works again. Further discussion can be found at https://software.intel.com/en-us/forums/topic/515943
