Bug ID: 463514
Summary: Valgrind not detecting the leaks.
Classification: Developer tools
Product: valgrind
Version: 3.13.0
Platform: Android
OS: Android 5.x
Status: REPORTED
Severity: major
Priority: NOR
Component: memcheck
Assignee: jsew...@acm.org
Reporter: shivaraju173ponnag...@gmail.com
Target Milestone: ---
Hello,
We have a target machine which is an arm 32-bit Android device. And
we tried to check the leaks on some essential services for our product. So we
choose the Valgrind for our kind of testing. But before proceeding, we want to
test the one sample application with memory leaks in it. And run the
application on top Valgrind in-arm devices but the leaks were not detected
through the Valgrind. Can anyone help me out with this issue?
Test Application:-
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <unistd.h>
int leak_func(void){
char *ptr = NULL;
ptr = (char *) calloc(1,20);
ptr = "Hello World\n";
printf("%s \n",ptr);
return 0;
}
int main(void){
int i=1;
printf("%s: Invoked\n",__func__);
leak_func();
while(i++)
sleep(1);
return 0;
}
compiled and pushed the above memory leak application into the arm platform
device.
#valgrind --tool=memcheck --leak-check=full --show-leak-kinds=all
--show-reachable=yes --track-fds=yes --trace-children=yes --track-origins=yes
--smc-check=all --extra-debug-info-path=path --log-file=/data/local/data.txt -v
/system/bin/<memory Leak app>
Observations:-
the leaks were not detected with Valgrind.
