yet another DLD question

[Andy+Alison Adler]

I've got this bizarre bug:

if I put my code

[SNIP]
   Octave_map As;
[SNIP]
   ColumnVector coefV=  As["coef"] . vector_value();
   double * coef =  coefV . fortran_vec();
   for ( int i= 0; i<  nnz; i++ )
      printf("a= %f\n", *(coef+i));
[SNIP]

then it works fine, giving output

a= 1.000000
a= 2.000000
a= 3.000000 
etc.


However, if I try to abbreviate by putting

[SNIP]
   double * coef =  As["coef"] . vector_value() . fortran_vec();
   for ( int i= 0; i<  nnz; i++ )
      printf("a= %f\n", *(coef+i));
[SNIP]

then the first value printed is always wrong
a= 39.399666
a=  1.000000
a=  2.000000  

(the first value is often 39.??? but is sometimes different)

MY QUESTION IS:

is As["coef"] . vector_value() . fortran_vec() illegal?
or is this a bug?
or am I doing something wrong

thanks
andy,
