copymemory not working in PB12.5.2

Hi All,

Copymemory not working in PB12.5.2, However it works well with the PB9.

Here is my code

Local external declarations are as follows.

SUBROUTINE CopyMemory(ref s_tvm_status dest, blob src, uint size) LIBRARY "kernel32" ALIAS FOR "RtlMoveMemory"

Please help on this scenario

Thanks

Raj
