Explanation of Func <p>I was wondering if someone could explain what <code>Func<int, string></code> is and how it is used with some clear examples.</p>

Assembly compilation error (gcc4.2.4=win, gcc4.3.3=fail) <p>We recently upgraded the code to <code>gcc4.3.3</code> from <code>gcc4.2.4</code>. </p>

"jc bitSet\n "
"movl $0, %1\n "
... | <p>Probably the optimizer has changed and is now inlining your testAndSet() function into 2 places. Because you are using global names for your labels, this does not work. You should use local names instead. E.g:</p>

"jc 0f\n "
"mov... |
