Public bug reported:
in src/zorbatypes/binary.cpp a lot of vectors are accessed with [0],
e.g.:
aBase64.theData.resize(
copy_without_ws( aString, aLength, &aBase64.theData[0] )
);
if in this case aLength is of size 0 the assertion "vector subscript out
of range" is hit on windows in debug build. This happens because size ==
pos in std::vector implementation on windows:
reference operator[](size_type _Pos)
{ // subscript mutable sequence
#if _ITERATOR_DEBUG_LEVEL == 2
if (size() <= _Pos)
{ // report error
_DEBUG_ERROR("vector subscript out of range");
_SCL_SECURE_OUT_OF_RANGE;
}
Therefore, before accessing a vector with [0] one must check whether the
size of the vector is > 0. Otherwise the mentioned assertion will
trigger.
