Error on basic Boogie file: "Function b is already defined." #444

Closed liammachado closed 5 years ago

liammachado commented 5 years ago

I'm getting a strange error when running Ultimate Automizer on a small Boogie file using the command ./Ultimate -tc config/AutomizerBpl.xml -s config/svcomp-Reach-64bit-Automizer_Default.epf -i t.bpl. I'm running release v0.1.24 on Ubuntu 16.04. I realize that many commits have been made since this release, so please disregard this issue if it's no longer present.

The Boogie file contents are shown below:

function b(int) returns (int);
axiom b(0) == 0;
procedure f() {
  assert true;
}

The error trace is show below:

This is Ultimate 0.1.24-91b1670
