MQL Help : Array resize -> Access violation write to...

Hi, the following test code crashes with the message:

2015.08.17 23:21:09.237 Access violation write to 0x920E3DA8 in 'C:\Users\Sabre\AppData\Roaming\MetaQuotes\Terminal\1DAFD9A7C67DC84FE37EAA1FC1E5CF75\MQL4\Experts\array_test.ex4'


Inserted Code
int OnInit() {
    float A[][1][1][1];
    
    ArraySetAsSeries(A, false);
    ArrayResize(A, 20);
    ArraySetAsSeries(A, true);
        
    A[0][0][0][0] = 0;
    
    return(1);
}
 
 
void OnDeinit(const int reason) {}
void OnTick() {}



If I comment line ArraySetAsSeries(A, false); it works. And if I use a 3 dimension array it works.
Do you know what the problem is? Thank you.

Jaime

The AS_SERIES flag ( call to ArraySetAsSeries) can't be set for multi-dimensional arrays or static arrays.

Maybe that's your problem.

Probably that's the problem.
Still, If I use an array with 2 or 3 dimensions, it seems to work and the debugger shows the "S" flag in the array after ArraySetAsSeries(buffer, true); ...
