Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

A simple for loop is causing the error. If I remove the for loop, then
there is no such error. The problem is the size of the arrays that I have
taken but I cannot reduce the size and so I am using external RAM. But the
problem remains.

Do what the output says and report the bug to the GCC bug database on the GCC web site: gcc.gnu.org
