Qemu 7.2.0 i386: core2: init crash (glibc)
Description of problem:
The toolchain-builder project (a side project of Buildroot to build pre-built toolchains) reported an issue with Qemu 7.2.0 for  x86-core2--glibc--bleeding-edge toolchain, see:

https://gitlab.com/buildroot.org/toolchains-builder/-/jobs/3731683337

Reverting back to Qemu 7.1.0, the system boot correctly with the same system image.
I reproduced the issue with the current Qemu master (6b433719eabf0abc74cff0cfd5687f0137c4198a)

Here is the boot log obtained with Qemu 7.2.0:

I did a git bisect on qemu sources up to this commit:

https://gitlab.com/qemu-project/qemu/-/commit/958e1dd1300f37f18b2161dfb4eb806fc8c19b44
Steps to reproduce:
Build the Buildroot qemu_x86_defconfig with BR2_x86_core2 target architecture variant added manually
1. git clone https://gitlab.com/buildroot.org/buildroot.git
2. git switch --detach c419ef62d84b5be65599452ab84f7ed719bbe470
3. make qemu_x86_defconfig
4. make menuconfig (enable BR2_x86_core2)
5. make
6. ./output/images/start-qemu.sh
Additional information:
System built with gcc options:
