pcap_findalldevs crashes - only when under Visual Studio debugger #393

When building a simple test example and running it under Win10 inside Visual Studio debugger, I get a crash on calling "pcap_findalldevs" or "pcap_findalldevs_ex". When running outside Visual Studio debugger, no crash and works as expected.

Not related to dll load as I have no such crash when trying to call other functions from npcap (such as pcap_remoteact_cleanup or pcap_wsockinit priori to the call, just for testing purpose). Same behaviour with delay dll loading or loading at startup.

Exception thrown at 0xF5203C2A in ***.exe: 0xC0000008: An invalid handle was specified.

From stack trace and debug symbols, I understand it occurs on line 593 of AdInfo.cpp, where ppItems is null and is dereferenced - only when executed inside Visual Studio debugger.

Known issue? What debug info would be useful to fix?
