Runtime Error, pure virtual function call -- what's going on?

Hi everyone,

Here is my problem. I use the Visual studio Fortran, but when the arrays (usually allocatable ones) has not been defined properly, it will show Runtime Error (as shown in the following image) and then close the working window. I want to know what's the reason for this error. I right use the 2012 version. When I used the 2010 version, I have never seen this error.

That's a Microsoft Visual C++ run-time error. Without seeing a test program that demonstrates the problem there's little more we can tell you, other than to suggest you're corrupting data by referencing unallocated arrays.
