Closed as program error.
When a large test case is undergoing a PDF2 link, it may encounter a internal compiler error in the xlCcode component of the compiler.
USERS AFFECTED: Any users compiling at O2 and up may encounter this issue. PROBLEM DESCRIPTION: Internal memory corruption is possible within the compiler. This may result in the compiler returning an internal compiler error; or it may result in bad code generation. In order for this issue to trigger; a certain optimization step has to complete exactly as the buffer in question is completely full and has not yet resized. The following optimization must then try to use that buffer before it is resized.
This is an internal memory issue within the compiler that has been fixed.
