From a code inspection of v5 of the patch (I haven't
actually run the patch anywhere), I'm a little uncomfortable
with the mixture of the two error handling styles (that is,
test-cleanup-return for most of the function, but
test-goto-cleanup for the one specific case). I don't mind
either style (and both are used in the Python source), but
mixing them in one function bothers me :)

Further, there appears to be a bug in the deallocation code,
in that all sequences should be freed with
adsl_seq_stmt_free. The current direct use of adsl_seq_free
means any contained statements are not released.

I suggest putting a single 'error' label at the end of the
function that uses adsl_seq_stmt_free to clean up all the
statement sequences , as well as free_stmt to clean up the
nested except statements. As both of these functions handle
nulls gracefully, the bodies of the current error cleanup
and return branches can all then be replaced with "goto error".
