Summary: BitVector's copy assignment triggers debug assert in
MSVC2010
Product: libraries
Version: trunk
Platform: PC
OS/Version: Windows XP
Status: NEW
Severity: critical
Priority: P5
Component: Support Libraries

MSVC2010 is a bit too aggressive in checking iterators (and pointers) for
validity when performing various algorithms in debug mode. This includes
verifying that output iterators that are pointers are not null. In the case of
std::copy it is conformant to pass a null pointer as an output iterator as long
as there are no elements to copy. However, I'd recommend changing this so that
std::copy is only called when there are elements to copy.
The relevant line is:
include/llvm/ADT/BitVector.h:332
