error in compiling commonSnippets.C

[aragagnin]

When compiling Extrae-3.7.1 with Dyninst-1.10.0, I get the following error:

commonSnippets.C:486:34: error: no match for ‘operator=’ (operand types are ‘Dyninst::InstructionAPI::Instruction::Ptr’ {aka 
‘boost::shared_ptr<Dyninst::InstructionAPI::Instruction>’} and ‘Dyninst::InstructionAPI::Instruction’)
  486 |         while((insn = dec.decode())) {

Looks like decode() returns a object Instruction while Extrae expects a Instruction::Ptr.
In fact, in the source code of Dyninst, we can see that the function signature returns a object:

$grep decode -A10 -B10  /opt/tools/dyninst-10.1.0//include/InstructionDecoder.h
[...]
class InstructionDecoderImpl;

class INSTRUCTION_EXPORT InstructionDecoder
{
  friend class Instruction;
    public:
    static const unsigned int maxInstructionLength = 16;
[...]
 /// Decode the current instruction in this %InstructionDecoder object's buffer, interpreting it as
  /// machine language of the type understood by this %InstructionDecoder.
  /// If the buffer does not contain a valid instruction stream, a null %Instruction pointer
  /// will be returned.  The %Instruction's \c size field will contain the size of the instruction decoded.
  Instruction decode();
[...]
