Test code:
------------
extern(C) int printf(const char*, ...);
struct S
{
this(int) { printf("ctor &this = %p\n", &this); }
int num;
}
S foo()
{
S s = S(1);
printf("foo &this = %p\n", &s);
return s;
}
void main()
{
auto s = foo();
printf("main &this = %p\n", &s);
}
Output:
------------
$ dmd -run test
ctor &this = 0012FE20
foo &this = 0012FE20
main &this = 0012FE20
------------
$ dmd -inline -run test
ctor &this = 0012FE1C
foo &this = 0012FE1C
main &this = 0012FE18 // variable is moved!
