First of all, thanks for looking into this.
The difference in our environments is:
gcc 4.3.2 32 bit x86 vs gcc 4.4.3 64 bit x86
So it could be either the 32 vs 64 bits or 4.3.2 vs 4.4.3
The following structure has a different layout between 32 64 bit
systems. I suspect that is when the problem shows up.
typedef struct {
off_t fs;
unsigned int i1;
unsigned int i2;
} TESTRIO;
I ran another test that included all the code in one module.
**** test file
#include <stdio.h> /* printf */
#define _FILE_OFFSET_BITS 64
#include <sys/types.h> /* off_t */
typedef struct {
off_t fs;
unsigned int i1;
unsigned int i2;
} TESTRIO;
int
rio_init(TESTRIO *rio){
rio->fs = (off_t)(-1);
rio->i1 = 1;
rio->i2 = 2;
return 0;
}
int
main(
int argc,
char *argv[]
){
TESTRIO rio;
rio_init(&rio);
printf("i1=%u, i2=%u\n", rio.i1, rio.i2);
return 0;
}
**** end test code
This in fact passed. So the problem is s subtle one and might be
related to linkage or whatever.
