Hello - I have been testing the MT5 platform for a few weeks, it is really very good and solid.
I have a very curious bug that I have discovered. Here is the minimal code to re-create it (as a script).
Basically, there is something awkward that happends when an array is resized in a different function that where the array was declared.
If you run the code below, the call to MathLog will cause an exception.
void funcalloc( double &x[], int n )
{
ArrayFree(x);
ArrayResize(x,n);
}
void OnStart()
{
double a[];
funcalloc( a, 100 );
a[8] = 2.45;
double res = MathLog( a[8] );
}
This is surprising because if a non-const reference is passed to a function, I should be allowed to resize the object, at least in C++
Best regards,
Edward
