The latest Green Card version behaves different from earlier versions.
E.g. the following a small example
--------------------------------------
import StdDIS
type Table = [Int]
%dis table x = stable x
%fun getTable :: IO Table
%code
%result (stable {the_table})
--------------------------------------
is converted to
--------------------------------------
import StdDIS
type Table = [Int]
getTable :: IO Table
getTable =
_casm_ ``do {int the_table; <= !!! HUH???
do {;
%r = the_table;} while(0);} while(0);''
>>= \ the_table ->
( deRefStablePtr the_table) >>= \ gc_res1 ->
(return (gc_res1))
--------------------------------------
the_table is a global C variable, but Green Card suddenly defines a
local variable with the same name. Bug or feature? If it's the latter,
how can global C variables be accessed from Haskell land now?
