    <p>I have ran into a problem compiling some template code with Visual Stuido 2010 SP1, cl.exe version 16.0.40219.1</p> <p>The following code will cause the compiler to access violate:</p> <pre><code>template&lt;typename T&gt; class A { A(){} }; template&lt;typename T&gt; class B : public A&lt;T&gt; { using A::A(); // Compiler access violates // **EDIT** //using A&lt;T&gt;::A&lt;T&gt;; // Compiler succeeds //using A&lt;T&gt;::A(); // Compiler reports error }; int main(int argc, char* argv[]) { return 0; } </code></pre> <p>It generates the following error (in addition to the "cl.exe has stopped working, C0000005 exception):</p> <pre><code>1&gt;d:\projects\cpptest\cpptest\cpptest.cpp(11): fatal error C1001: An internal error has occurred in the compiler. 1&gt; (compiler file 'msc1.cpp', line 1420) 1&gt; To work around this problem, try simplifying or changing the program near the locations listed above. </code></pre> <p>The code compiles fine (well, that is, it emits a proper error message and doesn't crash the compiler) in Dev-C++ with g++.</p> <pre><code>main.cpp:11: error: `template&lt;class T&gt; class A' used without template parameters main.cpp:11: error: expected nested-name-specifier before "A" main.cpp:11: error: using-declaration for non-member at class scope main.cpp:11: error: expected `;' before '(' token main.cpp:11: error: expected unqualified-id before ')' token make.exe: *** [main.o] Error 1 </code></pre> <p><strong>EDIT</strong> The following, however, compiles fine, without access violation, so it seems this is related to templates:</p> <pre><code>class A { A(){} }; class B : public A { using A::A; }; int main(int argc, char* argv[]) { return 0; } </code></pre> <p>Do you think this is worth reporting to Microsoft? Can anyone else reproduce this? Maybe try in Visual Studio 2013 to see if it still occurs?</p>

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.
