What does the error "Bar 0; array size is too large, maximum size is 100000" mean?

edit

This error means that the array specified in the code has a size that exceeds the maximum limit of 100000 elements. In other words, the program is trying to allocate more memory to the array than is permitted, causing the error to occur. This can happen if the program is processing a large amount of data or if the programmer has specified an array size that is too large.
