Stack overflow may refer to

• A stack overflow is a programming error when too much memory is used on the call stack.
  
• Stack buffer overflow, when a program writes to a memory address on the program's call stack outside of the intended data structure; usually a fixed length buffer
  
• Stack Overflow, a question-and-answer website on the topic of computer programming
  

check wikipedia

I think they referred to the website Stack Overflow. Stack Overflow as part of Stack Exchange has become a favorite go-to place for different programming questions. Check their help page.
