Since glibc 2.24, __malloc_initialize_hook is a compat symbol. As a result, the link editor does not export a definition of __malloc_initialize_hook from the main program, so that it no longer interposes the variable definition in libc.so. Specifying the symbol version restores the exported symbol.
