ArraySort() course memory crash

New comment
 
Hello,

I'm exploring various functions in MQL4 and found that the "ArraySort()" function would SOMETIMES cause memory crash, I've tried to use local array, global array, with or without size initialization, the function just crashes out of control !! (I got a memory dump screen with forced me to quit MT4 , and the last function called is ArraySort() everytime)

It seems that the memory allocation or garbage collection is designed with mistakes (in fact, I can't find any documentation about array memory allocation or garbage collection). May the development term put this issue in the next patch.

Thanks so much
 
this bug is fixed. thanx
