Hi everyone:
The most recent version of SAFECode is giving me trouble with very
simple test cases.
For instance, the program
int main()
{
int i[100];
i[101] = 10;
return 0;
}
when instrumented and run results in the following output:
SAFECode:Violation Type 0x6 when accessing 0x617934 at IP=0x401fc0
=======+++++++ SAFECODE RUNTIME ALERT +++++++=======
= Error type : Load/Store Error
= Faulting pointer : 0x617934
= Program counter : 0x401fc0
= Fault PC Source : main:6
=

= Allocated in Source File : main:1

SAFECode: Fault!

SAFECode: Fault!
SAFECode:Violation Type 0x9 when accessing 0xc0000001 at IP=0x411b64

SAFECode: Fault!
SAFECode:Violation Type 0x9 when accessing 0xc0000001 at IP=0x411b64
The last Unitialized / NULL Pointer Error statement is repeated without end.
Is there an explanation for this behavior and how can I get it to work
properly?
Thanks,
Matt
