----------------------------------------
Hi all,
I'm running macOS 15.2, and on my machine the test `TestGc#test_gc_stress_at_startup` results in an assertion failure.
These are my current configure flags:
```
../configure \
--prefix="$SOURCEDIR/ruby_3.4.1" \
--enable-debug-env \
--enable-devel \
cppflags="-DRUBY_DEBUG" \
optflags="-O0 -fno-omit-frame-pointer"
```
make command line for running tests (invoked from the build directory):
```
make test-all TESTS="../test/ruby/test_gc.rb --name=TestGc#test_gc_stress_at_startup"
```
output:
```
Run options:
--seed=7555
"--ruby=./miniruby -I../lib -I. -I.ext/common ../tool/runruby.rb --extout=.ext -- --disable-gems"
--excludes-dir=../test/.excludes
--name=!/memory_leak/
--name=TestGc#test_gc_stress_at_startup
