<div style="font-size: 16px; font-family: Tahoma; color: rgb(0, 0, 0); font-weight: 400; font-style: normal;">I went through all the "exx_*.f90" routines and it seems the problem was not what I mentioned in my last post. However, whatever the cause of the error is, it is in these routines (I do not know the exact reason). Maybe there is some small programming error which is ignored by newer versions of compilers?!</div>

<div dir="ltr">This is very unlikely, there are no calls to those intrinsic functions in EXX, and even if there were, they wouldn't cause an internal compiler error. Upgrade your compiler or ask your system administrator if you cannot.</div>
