Segemtation fault

[comfix]

I'm on ArchLinux with Lua 5.2.4 and when I try to run the emulator as you've described in the readme I get the segmentation fault. Had a LuaSec problem as of today (now its fixed) and therefor I recloned the repo and got this error.

What gcc version are you on? you can check with gcc --version If it's GCC 7, then it turns out luaffi has alignment issues with GCC 7. You can apply a patch to luaffifb's repo

clone luaffifb: git clone https://github.com/facebook/luaffifb; cd luaffifb apply the following patch: patch -p1 < gcc7.patch then run sudo luarocks-5.2 make

Since I believe that this is a GCC 7 issue, given that arch linux has gcc 7 in its repositories, closing.
