    <p>I have the following C++ file, pwd01.cpp:</p> <pre><code>#include &lt;pwd.h&gt; #include &lt;iostream&gt; int main() { passwd* pwd = getpwuid(getuid()); } </code></pre> <p>I compile this with the following command:</p> <pre><code>g++ pwd01.cpp -Wall -o pwd01 </code></pre> <p>On Ubuntu 12.04.1 LTS / gcc version 4.6.3, valgrind reports a leak (see below). When I compile the same code with the same command on Mac OS 10.6.8 / gcc version 4.2.1, valgrind reports no leaks. </p> <p>I am aware that I do not need to free passwd* ( <a href="https://stackoverflow.com/questions/160290/should-i-free-pointer-returned-by-getpwuid-in-linux">should I free pointer returned by getpwuid() in Linux?</a> ); so what am I missing? </p> <pre><code>valgrind ./pwd01 ==10618== Memcheck, a memory error detector ==10618== Copyright (C) 2002-2011, and GNU GPL'd, by Julian Seward et al. ==10618== Using Valgrind-3.7.0 and LibVEX; rerun with -h for copyright info ==10618== Command: ./pwd01 ==10618== ==10618== ==10618== HEAP SUMMARY: ==10618== in use at exit: 300 bytes in 11 blocks ==10618== total heap usage: 68 allocs, 57 frees, 10,130 bytes allocated ==10618== ==10618== LEAK SUMMARY: ==10618== definitely lost: 60 bytes in 1 blocks ==10618== indirectly lost: 240 bytes in 10 blocks ==10618== possibly lost: 0 bytes in 0 blocks ==10618== still reachable: 0 bytes in 0 blocks ==10618== suppressed: 0 bytes in 0 blocks ==10618== Rerun with --leak-check=full to see details of leaked memory ==10618== ==10618== For counts of detected and suppressed errors, rerun with: -v ==10618== ERROR SUMMARY: 0 errors from 0 contexts (suppressed: 2 from 2) </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
