In aarch64 board valgrind doesn't give c++ file or function name where memory is lost

Valgrind reports memory definitely lost along with file and function names in x86 machine as expected.

  1 #include<bits/stdc++.h>

  3 using namespace std;
  4 int main()
  5 {
  6     char  *name = new char[30];
  7     cout << "Enter name" << endl;
  8     cin >> name;
  9     cout << "Hi " << name << endl;
 10   //delete name;
 11     return 0;
 12 }

But the same code when ran in an aarch64 machine, valgrind doesn't report any info like file or function name, though memory definitely lost is being reported.

Anybody faced this in aarch64? How to get function, file names, line num.. in valgrind report for aarch64 or any such boards?

Note: valgrind and compiler versions are same in both x86 and aarch64.

Solution

  • Upgrading to latest valgrind version valgrind-3.20.0 resolved. x86 gives debug info without valgrind upgrade, only aacrh64 requires upgrade.

    Thanks @phd for your answer!!

    PS: If someone facing "valgrind is already the newest version" due to your linux distribution and want's to manually download/compile valgrind you can refer: How to install valgrind properly??
