For RCE exploits, there should probably be pluggable payloads, one of which can be the currently implemented shell loop. This would be ideal for networks with IDS/IPS when shell commands...

I believe this is caused by the negative offset that `size_` uses here https://github.com/stp/stp/blob/c68788eb05731ae08e4f730a6b1c93803620e2b9/lib/extlib-constbv/constantbv.h#L258 Shouldn't BitVector be a struct? and size, bits, and mask be fields? Instead of this negative...

@msoos I'm taking this on. It'll be pretty much a rewrite of constantbv.h and constantbv.cpp, and hopefully not too much outside of those two (perhaps some edits to things that...

Oof, understood. I can do that.

@TrevorHansen That sounds preferable. Either way, I need to work out a patch to avoid the segfault which this issue is causing. Somehow there's disconnect in the code where something...

After more digging, it appears that it pops up because the c_interface is handing nulls pointers downward which cause segfaults, due to type/kind confusion between booleans and bitvecs - also...

Understood. I'll take a look at hooking into the existing code which uses [vc_error_hdlr](https://github.com/stp/stp/blob/c68788eb05731ae08e4f730a6b1c93803620e2b9/lib/Globals/Globals.cpp#L47)

I'm not particularly familiar with error handling in C++, so anything would be pretty hacky :/ Thanks for the quick responses. EDIT: after a bit of googling, I might be...

If this could be exposed to the python API (although...

I'm unfortunately a bit stuck with Python2.7 at the moment, but Python3 has `faulthandler` which may replace this need if the binding is run under Python>=3.3: https://docs.python.org/3.7/library/faulthandler.html
