# In reply to @lainlaylie "i don't know about": Unfortunately, yes. And the
# exception handling there also kills the performance. Valgrind reports the
# current version of my code as:

==10413== Events    : Ir
==10413== Collected : 842808783
==10413==
==10413== I   refs:      842,808,783

# The same benchmark with the above code changes to:

==11739== Events    : Ir
==11739== Collected : 7807024852
==11739==
==11739== I   refs:      7,807,024,852
