Package: gcc-3.3
Version: 1:3.3.5-5
Severity: important
When compiling the included program with the mentioned versions of gcc,
wrong code is generated when using -O1 or -O2. See the comments in the
program, which I saved as test.c:
---------------------- CUT HERE -----------------------
/* This small program shows a bug in the optimizer of gcc.
* It occurs at least in these versions:
* - gcc (GCC) 3.3.4 (Debian 1:3.3.4-13)
* - gcc (GCC) 3.3.5 (Debian 1:3.3.5-5)
* It does not occur when the body of f is put directly in main.
* It does not occur when the "if" is split into two "if"s.
* It does not occur when -O0 or -O3 (or higher) is used.
* It only occurs if -O1 or -O2 are used.
* Output on my system with gcc (GCC) 3.3.5 (Debian 1:3.3.5-5):
* $ gcc test.c -o testbug
* $ ./testbug
* Address 0xff00 NOT in [0x4000,0xc000> (CORRECT)
* $ gcc test.c -o testbug -O1
* $ ./testbug
* Address 0xff00 in [0x4000,0xc000> (WRONG)
*/
#include <stdio.h>
void f(unsigned short ad)
{
if (ad >= 0x4000 && ad < 0xc000)
printf("Address 0x%x in [0x4000,0xc000> (WRONG)\n", ad);
else
printf("Address 0x%x NOT in [0x4000,0xc000> (CORRECT)\n", ad);
}
int main (void)

return 0;
