running the tests causes a core dump

[wluker]

I cloned ceu and followed the instructions given in README.md:

$ cd tst/
$ ./run.lua

and it errored out with

sh: line 1:  1180 Aborted                 (core dumped) /tmp/tmp.exe 2>&1
lua5.3: ./run.lua:364: >>> ERROR : run : expected "Aborted" : got ""
stack traceback:
	[C]: in function 'assert'
	./run.lua:364: in function 'Test'
	tests.lua:442: in main chunk
	[C]: in function 'dofile'
	./run.lua:572: in main chunk
	[C]: in ?

I'm running this on archlinux with lua-5.3.4-2. Is this version of lua too new?

The lua version is probably ok.
The tests should generate a /tmp/tmp.exe executable.
What do you get when you run it from the command line?

$ /tmp/tmp.exe 
Aborted (core dumped)    # <--- I get this string, which is the expected behavior

[wluker]

I also get the string

Aborted (core dumped)

I didn't understand that was the expected output. Sorry for the misleading title. Is this a shell script issue?

[fsantanna]

The run.lua executes a series of tests programs in tests.lua.
The first test is an empty program in tests.lua:442.
The empty program should fail because it terminates without a return value to the environment.
(The message is a "core dumped" because the trace option is turned off for this particular test case.)
I just don't understand why the run.lua is terminating if the result you get is exactly the expected result.
