test_functools fail during build of python3.13.3 with --enable-optimization and --without-docs-string

Hello, everyone.
I do not know if this is a normal behavior or a bug but,
I tried to compile python 3.13.3 with option : --without-doc-strings and --enable-optimizations
But it always fail during test_functools :

The same build environnement with python3.11 work fine.
If I remove one of --without-doc-string or --enable-optimizations the build work fine.

build setup :

• debian9
• glibc2.24

./configure --enable-optimizations --without-doc-strings --with-lto=full --disable-test-modules \
    --with-computed-gotos --enable-shared  \
    --enable-loadable-sqlite-extensions --with-ssl-default-suites=openssl --with-openssl=/openssl-3.2.0/ \
    --with-openssl-rpath=auto

make PROFILE_TASK="-m test.regrtest --pgo -j$CORE_NB" -j$CORE_NB;

Hello!
I guess this is fixed by cc39b19, could you please try it on current 3.13 branch (not 3.13.3)?

[vincentpichon]

Yep, it's working with the current 3.13 branch. Thank you.
