Bug#286239: gcc-3.3: I think sizeof(struct xxx) return wrong size

[BogDan <taipan@rdslink.ro>]

Package: gcc-3.3
Version: 1:3.3.5-3
Severity: critical
Justification: causes serious data loss

try to compile and run this

//-------------------------------
#include <stdio.h>

int main()
{
struct mesaj_primire
{
        unsigned char   xf;
        unsigned char   cf;
        unsigned char   nw;
        unsigned char   nl;
        unsigned int    posx;
        unsigned int    posy;
        unsigned int    state;
        unsigned char   nwc;
        unsigned char   nlc;
        unsigned char   crc;
        unsigned short  crc16;
};
printf("%i\n",sizeof(mesaj_primire));
return 0;
}

//---------------------------------
#gcc test.cpp -lstdc++ -o test
#./test
24

24!!!! and I think is 21

I try this on my ppc laptop and my x86 desktop and the result is the same (24)
