I think that you should/can, but it is your call. If you decide to open
a bug report, please also post gdb output of the following commands
(sanitized if needed):

-------------
set print pretty
set print-static-members off

bt full

frame 0
print cert
print *cert.raw
print *sig
print s

frame 1
print properties

frame 2
print request_message

Thank you,

Alex.
