i am using sdcc for last 5 months, but got this problem with union.

is union working properly with sdcc 2.6 and sdcc sdcc-20061129-4491 ???

Hi,

There is no bug here. All three union members start at _real_data in the asm.
Maybe you wanted something like:

union ab
{
unsigned int ab_main;
unsigned char ab_first[2];
};

or

union ab
{
unsigned int ab_main;
struct
{
unsigned char ab_first;
unsigned char ab_second;
} bytes;
};

In the latter bytes is optional for SDCC but not for all C compilers.
