The above code snippet compiles fine with SDCC 2.6.4, r4570.
_main_c_1_1 (alias c) ends up at 0x80, p=&c makes p=(0x80, 0x00, 0x80),
the first 0x80 (MSB) being the pointer type (0x80 --> __data), and
0x0080 being the address of c in data memory.
*p=0x12 assigns 0x12 to memory location 0x80 (alias c), which seems to
be perfectly fine. Tested with gpsim. Even reading back *p (glo = *p;
with a global `char glo;' declared before main()) works nicely.
Could you give more information? How did you `test *p' after the last
line of code? What did you perceive?
