What exactly is the -Warray-bounds option to the GCC compiler supposed to warn about?
the man page states:
Quote:
-Warray-bounds
-Warray-bounds=n
This option is only active when -ftree-vrp is active (default for -O2 and above). It warns
about subscripts to arrays that are always out of bounds. This warning is enabled by -Wall.
-Warray-bounds=1
This is the warning level of -Warray-bounds and is enabled by -Wall; higher levels are
not, and must be explicitly requested.
-Warray-bounds=2
This warning level also warns about out of bounds access for arrays at the end of a
struct and for arrays accessed through pointers. This warning level may give a larger
number of false positives and is deactivated by default.

It might be a simple one but I have this question bothering me for sometime.

binary.setblockdata
Binary.setBlockData(3kaya) Kaya module reference Binary.setBlockData(3kaya)NAME
Binary::setBlockData - Set the contents of a block.
SYNOPSIS
Void setBlockData( var Binary block, Int offset, [Int] bdata )
ARGUMENTS
block The binary block
offset The offset to start at (zero-indexed)
bdata The data to write, as an array of Int s
DESCRIPTION
Set the contents of (part of) a block from an array. An Binary.OffsetOutOfRange(3kaya) Exception will be thrown if this would cause a
write outside the bounds of the block. The following bits of code are equivalent:
setBlockData(block,offset,bdata);
// is equivalent to
for byte@idx in bdata {
poke(block,offset+idx,byte);
}
However, setBlockData is more efficient and checks bounds before any data is written - the above for loop could write partial data if off-
set+idx was greater than blockSize(block)
