Details:

Compiling attached file test.c with:
avr-gcc -mmcu=atmega32hvb test.c

And run the output with simulavr:
simulavr -d atmega32 -W 0x20,- -f a.out -T exit

Results in:
WARNING: file rwmem.cpp: line 124: Invalid write access to IO[0x8fb]=0x0,
PC=0xd0
WARNING: file rwmem.cpp: line 124: Invalid write access to IO[0x8fa]=0x1,
PC=0xd2
WARNING: file rwmem.cpp: line 115: Invalid read access from IO[0x8fa],
PC=0xd4
WARNING: file rwmem.cpp: line 115: Invalid read access from IO[0x8fb],
PC=0xd6
aWARNING: file rwmem.cpp: line 115: Invalid read access from IO[0x8fa],
PC=0xca
WARNING: file rwmem.cpp: line 115: Invalid read access from IO[0x8fb],
PC=0xcc

Repeating forever.  My understanding was that atmega32* parts should be
equivalent from a CPU standpoint and it would be reasonable to expect this to
work.  What am I missing?
