[Valgrind-users] About how to turn off the malloc hook

[shuai xi <aha...@gm...>]

 hello developers,
I want to reuse the shadow memory part of  memcheck , but do not want to
use the malloc hook part.
When I set the 'VG_(needs).malloc_replacement = False',the malloc hook
part  seems still to be working.
Which code do I need to modify to make malloc replace invalid?
