<pre>If an allocator is not specified for a list constructor call, the allocator
used should be the lists allocator. It seems this is not the case for libc++
Consider the following from a cygwin cut/paste where the g++ library seems to
do the right thing, but libc++ does not:
$ cat t.cpp
#include <list>
#include <memory>
#include <cstdio>
struct myalloc : public std::allocator<int> {
myalloc() { printf("in ialloc\n"); }
};
int main(void)
{
// This should use the myalloc allocator, it does not
std::list<int,myalloc> c00((std::list<int,myalloc>::size_type) 3);
}

$ clang++ -o a.out t.cpp
VogelEd@XLB3502Q4E ~
$ ./a.out
in ialloc
VogelEd@XLB3502Q4E ~
$ clang++ -o a.out -stdlib=libc++ t.cpp
VogelEd@XLB3502Q4E ~
$ ./a.out
VogelEd@XLB3502Q4E ~
Not an important problem, but one found by our verification tests.
Thank you,
