which versions are you using (
SonarQube:sonarqube-6.7.1 (developer-edition-6.7.1.708).
Scanner: sonar-scanner-cli-3.0.3.77.
Plugin: sonar-cfamily-plugin-5.0.0.9359.jar.
and any relevant extension:no)
what are you trying to achieve:I hope that Sonar can help us detect the problem of this array out of bounds.
what have you tried so far to achieve this：I am using C/C++ language,I tried to analyze the following simple code, which has an obvious array out of bounds problem, but sonar did not detect it, no report. This issue is very important to us, I hope that Sonar can detect it.
int testbuff[100] = {0x00};
int n = 0;
for(n=0;n<200;n++)
{
int x = testbuff[-100];
printf(“test err=%d\n”, x);
if(testbuff[n-1] == 0xFF)
{
printf(“test err\n”);
｝
else
{
printf(“test ok\n”);
}
}
I would recommend you to upgrade to the latest version of sonar-cfamily-plugin which is version 6.0.
In any case, in general we cannot ensure to spot every bug, we do our best to improve our analyzer constantly.
Hi, Massimo Paladin
I have upgraded sonar-cfamily-plugin to version 6.0, which is to replace sonar-cfamily-plugin-5.0.0.9359.jar with the latest sonar-cfamily-plugin-6.0.0.10816.jar. But when using the sonar-scanner, I got an error. The error message is as follows:
