           Summary: Abort trap in Kaleidoscope/toy example,  "at the end"
           Product: new-bugs
           Version: 2.6
          Platform: Macintosh
        OS/Version: MacOS X
            Status: NEW
          Severity: normal
          Priority: P2
         Component: new bugs
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: albert at mietus.nl

The toy-example, build WITH interpreter (and probably without a working native
lib; see emails) seems to work, until one terminates the program with
end-of-file, (either ^D or ^Z)

As can be seen below, this results in a abort-trap.

This happens both with the 2.6 "PreBuid" (apple OS X 10.5.8)  and a "self build
2.6 Debug" (same) libs.
