Stacktraces omit the function that was called

[russell]

Hey,

It can be really hard to debug expressions when there are more than one or 2 function calls 😭

Using the test program

local identity(a) = a;


local foo = {
  bar(a): (
    assert false;
    a
  ),
  baz(): self,
};

foo.baz().bar(identity(1))

when running the golang version, the top of the stack is missing, so the information we have to debug this is that somewhere on the line foo.baz().bar(identity(1)) there is an issue.

$ jsonnet test.jsonnet
RUNTIME ERROR: Assertion failed

        test.jsonnet:12:1-27    $
        During evaluation

from the c++ implementation, indicates what function call resulted in the error, that indicates that the error came from this part of the file

    assert false;
    a

$ jsonnet test.jsonnet
RUNTIME ERROR: Assertion failed.
        test.jsonnet:(6:5)-(7:6)        function <anonymous>
        test.jsonnet:12:1-27

Thanks for reporting. I have a change underway that should fix issues like that. I will check that it fixes specifically your example, too.
