Unfortunately, the backtrace isn=E2=80=99t helpful because of threads, and I
can=E2=80=99t reproduce it.

Could you replace =E2=80=98par-map=E2=80=99 with =E2=80=98map=E2=80=99 and =
try again?

You can also add =E2=80=98pk=E2=80=99 calls in =E2=80=98lookup-narinfo=E2=
=80=99 and similar to get more
details.

TIA,
Ludo=E2=80=99.
