Give me an example of such an expression. A reproducible one. Then you will be able to say something.

ulong PackMagic(int bs, int type, int frac, int ll)//bs=0 - sell, bs=1 - buy (в смысле ll), type - это тип FPST
     {
        int d1;
        ulong i, frac1=frac, ll1=ll, type1=type;
        
        i=1; d1=10;
        while (ll>=d1) {d1=d1*10; i=i+1;}
              
        if (type==0 || type==2) return (frac1+ll1*Pow10frac_length+i*Pow10(frac_length+i)+
         type1*Pow10(frac_length+i+1)+bs*Pow10(frac_length+i+2)+Id1_class*Pow10(frac_length+i+3));
        else return(ll1+i*Pow10(i)+type1*Pow10(i+1)+bs*Pow10(i+2)+Id1_class*Pow10(i+3));
     }    
    
     ulong Pow10(ulong power) // power>0
     {
        ulong r=10;
        if (power==0) return 1;
        for (ulong i=2; i<=power; i++) r=r*10;
        return r;
     }

The problem is in the PackMagic function. external variables int frac_length=2; int Pow10frac_length=100; int Id1_class=1;.

You didn't provide an example of the error. At which argument values does this function return the wrong value (which one?) and what should be the correct result?

For example:

Id1_class=1, bs=0, type=0, frac=99, ll=1, frac_length=2, Pow10frac_length=100, return returned 11299.

It should be 1001199. In Expert, functions in class, demo account in Open.

It's not a fact that 11299 will always be returned in case of an error.

 
Not reproducible. With these parameters, the function stably returns 1001199. There are no errors in the function itself either. So, there is nothing to say. Most likely, the problem in your Expert Advisor is not in this function, but somewhere else. The values of the parameters passed to the function are different from those you expect. Accordingly, the result is different from the expected one.
 

It's playing. Wrote your code to script, it gave correct value (1001199) when run in debug mode, but if I compile release and run it from tree in MT5, it gave 11199 steadily. I was able to localize the problem, here is the reproducing code:

int frac_length = 2;

void OnStart()
{
        
        ulong i = 1;

        ulong a1 = Pow10(frac_length + i);
        ulong a2 = Pow10(frac_length + i + 1);
        ulong a3 = Pow10(frac_length + i + 2);
        ulong a4 = Pow10(frac_length + i + 3);
        
        Print(IntegerToString(a1), " ", IntegerToString(a2), " ", IntegerToString(a3), " ", IntegerToString(a4));

}  

ulong Pow10(const ulong power)
{
        ulong r = 10;
        
        if (power == 0)
                return 1;
                
        for (ulong i = 2; i <= power; i++)
                r = r*10;
                
        return r;
}

In debug mode it works correctly. But at start of release from navigator in MT5 either it produces nonsense ("1000 10000 100 100 100" instead of "1000 10000 100000 1000000") or MT5 hangs with full load of one of cores of the processor.

There are two ways to fix it. Either of these ways:

        ulong a1 = Pow10(frac_length + i);
        ulong a2 = Pow10(frac_length + i + (ulong)1);
        ulong a3 = Pow10(frac_length + i + (ulong)2);
        ulong a4 = Pow10(frac_length + i + (ulong)3);

Either by moving global variable frac_length inside Start() function.

This is indeed a compiler bug, write to Service Desk.

 
MT4 started to weigh 1.8 gigabytes (RAM). It ate all the UPU, the second terminal cannot be switched on properly. Can you tell me how to "clean" the RAM from MT?
