"i say already again i do not clik the stop build button!!!"
It's not talking about you interrupting the build process!
The concept of Imterrupts is absolutely basic to just about all computers - they go by the name of "IRQ" on PCs (short for "interrupt request")

"i thinking is big bug in compiler !!!!????"
No - just a big hole in your understanding
