Progress in porting to 1.7, but still work to do

Progress in porting to 1.7, but still work to do

[Bruce Korb]

I have *two* problems.  First, after emitting the error text below,
Guile 1.7.2 is calling, "exit(0)" not "exit(EXIT_FAILURE)".
That's wrong.  Additionally, I am not getting the file/line
stuff using the code I thought we worked out.

Wasn't this supposed to work?

    SCM port = scm_open_input_string( scm_from_locale_string( pzExpr ));

    {
        static SCM file = SCM_UNDEFINED;
        static char* pzOldFile = NULL;

        if ((pzOldFile == NULL) || (strcmp( pzOldFile, pzFile ) != 0)) {
            if (pzOldFile != NULL)
                free( pzOldFile );

            pzOldFile = strdup( pzFile );
        }

        file = scm_from_locale_string( pzFile );
        scm_set_port_filename_x( port, file );
    }

    {
        SCM ln = scm_from_int( line );
        scm_set_port_line_x( port, ln );
    }

    {
        SCM ans = SCM_UNSPECIFIED;

        /* Read expressions from that port; ignore the values.  */
        for (;;) {
            SCM form = scm_read( port );
            if (SCM_EOF_OBJECT_P( form ))
                break;
            ans = scm_primitive_eval_x( form );
        }

        return ans;
    }

What function in Guile is calling exit?

Can you post the code that is being evaled (or a simpler example that
shows the same problem)?  I think that means whatever pzExpr is in the
following code.

None.  gh_enter is returning when an error gets thrown.
(See the followup message to the one you replied to.)
My original code ended with:

    /* NOTREACHED */
    return 0;

Now, it ends with:

    /* sometimes reached */
    abort();
    return 0; // silence picky compilers

It seems to be a general problem.  I've now seen messages from at least
two people complaining about the lack of file/line information.

Thank you, Neil.   Regards, Bruce
