I am facing problem in an image processing program.

The attached file avr1.c in avr1.zip when executed with the following
command line produces the error Unrecognizable insn.

avr-gcc -mmcu=atmega128 avr1.c

avr1.c: In function `main':
avr1.c:16: error: unrecognizable insn:
(insn 29 27 73 0 0x400178c4 (set (reg:HI 55)
        (const_int 44838 [0xaf26])) -1 (nil)
avr1.c:16: internal compiler error: in extract_insn, at recog.c:2175
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.

Thanking you,
