Test case
m32c-elf-gcc (GCC) 4.7.2 hosted on Windows XP.
If I compile and run the attached program with:
m32c-elf-gcc -msim -mcpu=m32c -O1 -DDATASIZE=126 stack.c
m32c-elf-run a.out
it works well. But if I increase DATASIZE to 127:
m32c-elf-gcc -msim -mcpu=m32c -O1 -DDATASIZE=127 stack.c
m32c-elf-run a.out
the program crashes.
