Hmm.. Looking at the assembly code it looks like the panic comes from the
"saved_facts.MaxTargets + saved_facts.MaxVolumes" calculation - saved_facts has
been deallocated somewhere?
1f75: e8 e6 2a 00 00 call 4a60 <mpr_iocfacts_free>
1f7a: 0f b7 85 58 ff ff ff movzwl -0xa8(%rbp),%eax
1f81: 0f b6 b5 5f ff ff ff movzbl -0xa1(%rbp),%esi
1f88: 01 c6 add %eax,%esi
