The following code run as expected when compiled with the 64 bit compiler.

With the 32 bit compiler, an access violation occurs when printing hypot(x2,y2).

Code:
program test
implicit none
real   x1, y1, z1
real*8 x2, y2, z2
  x1 = 3.0
  y1 = 4.0
  z1 = hypot(x1,y1)
  print*, x1, y1, z1
  print*, x1, y1, hypot(x1,y1)
  x2 = 3.d0
  y2 = 4.d0
  z2 = hypot(x2,y2)
  print*, x2, y2, z2
  print*, x2, y2, hypot(x2,y2)   !Problem occurs here with 32 bit compiler
end program test

This bug has now been fixed for the next release of FTN95 and salflibc.dll (after v9.0).
