; Derivated bug : same bad behavior than in CALL_PROCEDURE
; Bug reporte by F. Galliano, mid-February 2016
; Detected using MPFIT ...
;
; contents of structures transported by _extra may change
; if the names are "too close", depending the order ...
; struct = {c:0, baaa:1, babaa:2, baba:[3,2]} <-- NOT OK
; struct = {c:1, baaa:1, baba:[3,2], babaa:2} <-- OK
;
function THE_FUNCTION, x, p, y, _EXTRA=extra
;
common flag, error
;
print, 'INSIDE THE_FUNCTION'
HELP, /STRUCT, extra
;
expected={c:0, baaa:1, babaa:2, baba:[3,2]}
;
ok=ARRAY_EQUAL(extra.baba, expected.baba)
if (ok NE 1) then begin
print, 'FATAL : fields in structure changed !!'
error=1
