• admoises Compiler bug?

  I get incorrect results when running this app built release. It should print "a=1, b=2" but in release it prints "a=1, b=1".

First of all I'd like to use a stable and tested product, not a beta one, so I excluded the upcoming 2005, because the Beta 2 version to which I gave a try presents a long list of bugs and annoyances at the moment, and there's too much uncertainty on its real final release date. So let's go ...Show All
