Running

def test() -> i32:
    temp: i32 = 0
    return temp

x : i32 = test()
# print(x)  Will give segmentation fault

gives code generation error: Function code not generated for 'test' .

But declaring and assigning in different line

x : i32
x = test()
print(x)

compiles successfully.
Not sure if this is intentional. This type of code runs fine in CPython.

   That's a bug, in fact two separate bugs, one a segfault, the other one "code generation error: Function code not generated for 'test'", both need to be investigated and fixed. Given how simple the code is, I think this is a high priority bug, so I put it into our roadmap: #1600. Thanks for reporting it!

   I think, I can see two issues here:
   1.

   def test() -> i32:
       temp: i32 = 0
       return temp
   
   x : i32 = test()

   The above code doesn't have any statements, so function-call to _lpython_main_program is not happening
   2.

   def test() -> i32:
       temp: i32 = 0
       return temp
   
   x : i32 = test()
   print(x)

   Here x is a global_variable and we are initializing it using a function call. I think that is the reason for the seg_fault.
