Me too. It's also hard to track down when in a Windows DLL.
Especially when it's timing-related and only exposed intermittently by 
hardware.
Having just tried some hacking of the DMD source, I can confirm that 
they're indeed really easy to track down when you're writing a compiler. 
Unfortunately, not all situations are so easy.
