run time error forrtl:severe <8>

[Hanbing_P_]

    Recently, I always meet the run time error "forrtl : severe <8>: internal consistency check failure, file for_intrp_fmt.c, line 1474" when using IVF 2013 integrated with VS2012. The error appears and disappears strangely, which means it doesn't appear every time but sometimes, and once it appears , it may disappear after I clean up the solutions several time but this way does not work out every time. So, it has almost driven me crazy because I know nothing about how to figure it out .I am looking forward some possible solutions about it . Thanks a lot! By the way ,even though the error appears randomly ,but it always occurs at file I/O expression like this:''  READ (iunit,'(i6,14x,a)') iver,line ''(I am sure of the consistency of the format in the file with the format description )

We have not yet been shown code that allows us to reproduce the error. Secondly, in your original description in #1, you have the self-contradictory and confusing statement, "I always meet the run time error ... The error appears and disappears strangely, which means it doesn't appear every time but sometimes". Thirdly, the function subprogram in question is superfluous because the new Fortran feature, "NEWUNIT=" is already available do what the problematic function is supposed to do.

It is not possible for me to give any more useful suggestions in such a situation.
