With the 32-bit build and +wpcap the "Unknown options specified" is visible, and tracing network packets seems to work.
That's expected. PCAP_MMAP_32BIT is only needed in a new WoW64 build.
This size of 0x3c141000 seems to be nearly a quarter of the whole address space of a 32-bit process, which would need to be available in one contiguous block?
Assuming this works on Windows it would be interesting to try a new WoW64 build. Perhaps enough memory will be available there when native libraries are mapped above the 32-bit limit.
