Dear All,
I define an array inside a function.
Unfortunately, all the elements of the array initialized by 0x30,
instead of the given values.
The array can placed in __code, but has the same behaviour.

SDCC : pic16/pic14 2.8.4 #5250 (Oct 12 2008) (UNIX)
The function:
//----------------------------------------------------
unsigned char conversion_by_table(unsigned char index)
{
unsigned char conversion_table[4] ={'0x01','0x02','0x03','0x04'};
return conversion_table[index & 0x03];
}
//----------------------------------------------------
The generated code:

S_main__conversion_by_table code
_conversion_by_table:
