-
Smart Pointers:
-
New Features:
-
Glen Fernandes provided implementations of make_shared and
allocate_shared for arrays. They achieve a single allocation
for an array that can be initialized with constructor arguments
or initializer lists as well as overloads for default initialization
and no value initialization. See the 'make_shared
and allocate_shared for arrays' page for more information.
-
shared_ptr
can now be used to hold a pointer to a dynamically allocated
array. This is accomplished by using an array type (T[]
or T[N])
as the template parameter.
-
Smart pointers now use
explicit
operator bool
on C++11 compilers. This can break code that passes a smart
pointer to a function taking a bool,
or that returns a smart pointer from a function with a bool return type. Please use
p !=
0 or !!p in such cases.
-
StringAlgo:
-
Fixed a bug where it wouldn't find overlapping patterns (#7784).
-
Disambiguated some calls to insert (#7346).
