[avr-gcc-list] Understanding Problem or Error with ++ Operator

[Dirk Hoffmann]

Hi folks,
I have a problem like this:
This code is working, as i expect, it adds one to CurSektor, 
void FAT_NextSektor ( unsigned long *CurCluster, unsigned long *CurSektor ) 
{
        [...]
        *CurSektor= *CurSektor+1;
        [...] 
}
But I wrote it before as:
void FAT_NextSektor ( unsigned long *CurCluster, unsigned long *CurSektor )
{
        [...]
        *CurSektor++;
        [...] 
}
This increments the pointer SurSektor by 4.
The same compiler output as CurSektor++;
