hello,

I run euphoria 4 (r3379) on windows Vista.
i've tried to compil my euphoria project and obtained this error :

eugrid.c(6849): Error! E1014: Left operand must be an 'lvalue' 
eugrid.c(6851): Error! E1014: Left operand must be an 'lvalue' 

the interested lines of eugrid.c are

int _44EGW_LoadData(int _id_65739, int _data_65740, int _insert_position_65741) 
{ 
    int _grid_65742;

    int _35975; 
    int _35974 = 0; 
    int _35973 = 0; 
    int _35972 = 0; 
    int _35971; 
    int _35970 = 0; 
    int _0, _1, _2; 
     
 
    /**         rows = 0*/ 
    _rows_65743 = 0; 
 
    /**         inserted_at=-1*/ 
    _inserted_at_65744 = -1; 
 
    /**         rows = length(data)*/ 
    if (IS_SEQUENCE(_data_65740)) 
        0 = SEQ_PTR(_data_65740)->length; 
    else 
        0 = 1; 
 
    /**         grid = EGW_GetGridID (id)*/ 
 
    /**         return ( find(id, GridID) )*/ 
    _grid_65742 = find_from(_id_65739, _44GridID_64085, 1); 

eugrid.c come from eugrid.e and the translation error come from EGW_LoadData function :

-- EGW_LoadData: Load table dataset 
--*------------------------------------------------------* 
global function EGW_LoadData ( integer id, sequence data, integer insert_position ) 
 
        integer grid, rows, inserted_at 
 
        rows = 0 
        inserted_at=-1 
 
        -- get number of rows to insert 
        rows = length(data) 
 
        -- get grid id 
        grid = EGW_GetGridID (id) 

To resolve this translation error, i've deleted the code line :

        rows = 0 

I obtained a good eugrid.c source file and the euc process went to the linking step...hum strange. I decided to make a test with the assignment statement and wrote this small program :

function test1length(sequence data) 
integer l 
 l = 0 
 l = length(data) 
 return l 
end function 
 
sequence a 
integer b 
a ="ceci est un test sur la longueur d'une chaine de caractères" 
 
b = test1length(a) 
 
printf(1,"longueur de a:[%d]\r\n",{b}) 
 
if getc(0) then 
end if 

the execution of the interpreted version is OK. So i tried to compile the program and i obtained this error :

Is it a problem from my computer ? or VISTA ? or Euphoria version ? or the DEP proctection (set only for windows programs and windows services) ? or the installation of Euphoria version ?

i've seen the bug referenced by the ticket 201 and my problem is :
with or without the assignement statement in the function test1length of the small program, i can't translate it to obtain a source C file.
