Compiler Internal Error of ifc7.0 in compilation of Vasp

[lensoftruth]

When I compiling the version vasp4.6, ifc7.1,mpich-1.2.5, on Redhat advanced ws server 3.0 (using p4 CPU), the compiler report the following error:

...

Internal Error: 0_1202
*Compiler Internal Error* : Please report to Intel Corporation
compilation aborted for mpi.f90 (code 1)
make: *** [mpi.o] error 1

How can I do with it?

Note that I have to use ifc 7.0 because the software states that theydidn't support higher verison of ifc.

The only reason a newer compiler wouldn't work is the case where you might be using .o files compiled with 7.1 or earlier. Saying that a recent compiler isn't supported sounds to me like support has been withdrawn. Other options, which no doubt have occurred to you, would be splitting the source into individual functions, and choosing less ambitious optimization flags for troublesome functions. If you have such a failure with 9.0 or 9.1, you can report it and ask for a bug fix, but if you stay with 7.1 you can do no more than make sure you have the latest version of it.
