Two more Windows-related fixes:
...
- More enum signeness bitfield fixes (MSVC treats enums as signed).
- Fixed in Lex/HeaderSearch.cpp an unsafe copy between two
HeaderSearch::PerFileInfo entries in a common vector. The copy involved two
calls to getFileInfo() within the assignment; these calls could have
side-effects that enlarged the internal vector, and with MSVC this would
invalidate one of the values in the assignment.

Patch from Argiris Kirtzidis:
...
The patch fixes some debug assertions that the msvcrt throws:
1)
- if (isprint(value) && value < 256) {
+ if (value < 256 && isprint(value)) {
isprint() does an assertion check of its own for value < 256; check value before calling it to prevent it.
2)
- Stmt->Names.push_back(std::string(&data[0], data.size()));
+ if (data.size() == 0)
+ Stmt->Names.push_back(std::string());
+ else
+ Stmt->Names.push_back(std::string(&data[0], data.size()));
If data.size() == 0 then data[0] throws "out of range" assertion.

Major cleanup of path-sensitive analysis engine and the current analysis
...
based on constant. prop. and limited symbolics.
- Renamed class: RValue -> RVal, LValue -> LVal, etc.
- Minor method renamings and interface cleanups.
- Tightened the RVal "type system" so that UninitializedVal and UnknownVal
cannot be cast to LVal or NonLVal. This forces these corner cases values
to be explicitly handled early before being dispatched to plug-in transfer
function logic.
- Major cleanup in the transfer function logic for binary and unary operators.
Still fixing some regressions, but we now explicitly handle Uninitialized
and Unknown values in a more rigorous way.

When creating the CFGBlocks for a switch statement, we now have the "default"
...
branch ALWAYS be the last successor for a switch-terminated block. This allows
clients to distinguish cases like the following:
switch(...)
case XXX:
switch(...) {
case YYY: ...
}
case ZZZ: ..
}
In this case, the block with "case ZZZ:" is the default block for the inner
switch statement, but that case is associated with the outer switch statement,
and not the inner one. Clients can test for this behavior by checking if a
successor block is the last one (and thus just assume that this is the "default"
case).
