Preload libjemalloc.so for long-running Ruby (#16462)
Always mark jemalloc needed if jemalloc is enabled by akihikodaki · Pull Request #4627 · ruby/ruby https://github.com/ruby/ruby/pull/4627 > Symbols exported by jemalloc is referred by the shared library but not > by the executables when building Ruby as a shared library with > jemalloc. It causes shared libraries such as the GNU C++ library > occasionally rely on the memory allocator provided by the standard C > library. Worse, the resolved symbols can later be replaced with > jemalloc, and jemalloc may see pointers from the standard C library, > which results in various failures. > e.g. https://github.com/tootsuite/mastodon/issues/15751 As a workaround, do not rely on jemalloc enablement of Ruby, and preload libjemalloc.so instead.
