A customer had a program that was corrupting the managed heap by p/invoking incorrectly. The problem didn't show up until the next garbage collection pass, at which point the CLR got all freaked-out-like. "According to Knowledge Base article 286470, the tool is supposed to catch heap corruption, but it doesn't catch squat." Depending on your po...

When you answer, a synthesized voice says that they are calling from JPMorgan Chase MasterCard security. They claim that your credit card has been disabled due to suspicious activity, and in order to re...
