Test failures were my local system and related to the stack 
overflow tests.


I have the build pipeline up and running but hit a couple of 
snags.

https://github.com/JesseKPhillips/lua/runs/493866555?check_suite_focus=true

* Couldn't use dpp in the build because I couldn't install 
libclang-dev on the runner (ubuntu repository issue)

* The compiler couldn't locate libphobos

I think I'll be able to make use of dpp locally though.

I am only guessing, but I think the problem is line 87.
Arrays and slices in D contain a length field and thus do not 
need to be null terminated.
The foreach at line 96 iterates on all valid indices and thus 
in the last iteration you call luaL_requiref(L, null, null, 1).


Try changing

static const luaL_Reg[] loadedlibs = [
  ...
  {LUA_DBLIBNAME, _debug},
  {null, null}
];

to

static const luaL_Reg[] loadedlibs = [
  ...
  {LUA_DBLIBNAME, _debug}
];


I knew I was blind, thank you. Segfault is gone.

Now I should look at getting the CI up and Test failure fixed.

I have chosen to do this file by file and attempting to start 
with linint. I wanted to make use of dpp, however I hit a 
segmentation fault and reduced dependency.


https://github.com/JesseKPhillips/lua/blob/dpp/init/linit.d

I wasn't able to get a core dump for debugging. Anyone willing 
to give some advice or solution? I have gone through a number 
of compilers and better.


I have implemented a build pipeline but didn't incorporate the 
D portion at this time.
