--- Comment #5 from mike <maware at ucsc.edu> ---
This is the binary build of 11.2p9 (working) and 11.3p2 (non working) with
netmap and ixgbe built in to kernel. Nic is 82599 (intel x520). Using Bro/Zeek
2.6.3 with bro-netmap plugin. Issue seems to really trigger once it starts
pulling packets from the buffers which seems to trigger the out of bounds
pointer. 

Nic output in dmesg:

ix2: <Intel(R) PRO/10GbE PCI-Express Network Driver, Version - 3.2.12-k> port
0x8020-0x803f mem 0xca080000-0xca0fffff,0xca104000-0xca107fff irq 64 at device
0.0 numa-domain 1 on pci21
ix2: Using MSI-X interrupts with 17 vectors
ix2: Ethernet address: ac:1f:6b:2d:f2:3c
ix2: PCI Express Bus: Speed 5.0GT/s Width x8
ix2: netmap queues/slots: TX 16/4096, RX 16/4096
ix2: permanently promiscuous mode enabled


Please let me know anything else I can include to help.
