Bug ID: 34513
Summary: Missing DW_OP_deref for non-trivial return by value
Product: libraries
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: DebugInfo
Assignee: unassignedb...@nondot.org
Reporter: dblai...@gmail.com
CC: apra...@apple.com, llvm-bugs@lists.llvm.org,

Try this in a debugger:
struct string {
string() {}
string(int i) : i(i) {}
~string() {}
int i = 0;
};
string get_string() {
string unused;
string result = 3;
return result;
}
int main() { get_string(); }
$ clang++ -g -fno-exceptions str.cpp
$ gdb ./a.out
b 10
r
p result
p *(string*)result
Looks like there's a missing DW_OP_deref in here somehow.
