Today I found that the current 3.4-dev is unable to build with jemalloc activated, while 3.3.4 or any lower versions can be build as usual with or w/o jemalloc activated.

• macOS Sequoia: 15.1.1 (M3 Chip)

• env (FYI: --with-opt-dir=$(brew --prefix jemalloc)" does not affect the result):

export RUBY_CONFIGURE_OPTS="--disable-install-doc --disable-shared --with-jemalloc --with-opt-dir=$(brew --prefix jemalloc)"
export LD_PRELOAD=`jemalloc-config --libdir`/libjemalloc.dylib

• setup:

$ pkgutil --pkg-info=com.apple.pkg.CLTools_Executables
package-id: com.apple.pkg.CLTools_Executables
version: 16.1.0.0.1.1729049160

As far as I checked gc.c, at least HAVE_MALLOC_USABLE_SIZE and HAVE_MALLOC_TRIM directives are missing in 3.4-dev (see the attached).
I hope these information would help resolve the issue 🙏

Thank you in advance,
