Yup, -fbounds-check, and it only works for local arrays. Once the array is
passed to a function, poof! no more bounds checking.
No.
Please read the links.
There are solutions that do full checking by checking every pointer access at
runtime. And there are other solutions.
Yeah, I looked at them. For example,
http://www3.imperial.ac.uk/pls/portallive/docs/1/18619746.PDF has the money quote:
"The ’A’ series, which is a group of classic artificial benchmarks, and the ’B’
series, which is a selection of CPU-intensive real-world code, performed
particularly poorly, ranging from several hundred to several thousand times slower."
This is not a solution. C has successfully resisted all attempts to add bounds
checking.
