I have a question in regards semi-dual use of dynamic and static jemalloc.
What happens if jemalloc is LD_PRELOAD'ed for an executable where such
executable uses a .so library, which in turn is statically linked with
Does this result in two jemalloc instances running, each managing part of
heap, neither having a complete view of the system etc.?
Use case example;
LD_PRELOAD....jemalloc... mysqld # where msyqld uses TokuDB .so lib
and this lib has jemalloc statically linked.
