Memory Clean Problem

New comment
 

Hello,

there is a problem with memory clean for arrays in MT5. My Build is 1931 and if you run this code in backtesting you can see that memory(RAM) increase to maximum allowed.

There is no service desk anymore, you'll need to comment on the version release thread. Also, this bug is from StringSplit... you should be seeing "n leaked strings" in the log.
