Description

As reported in #17410 (see https://github.com/RIOT-OS/RIOT/pull/17410#issuecomment-997771008), some tests are failing on stm32l5 (and on stm32u5):

tests/malloc works when the firmware is built with GCC 9.

Steps to reproduce the issue

make BOARD=nucleo-l552ze-q -C flash test

Expected results

The tests pass

Actual results

The tests fail (see details above)

The problem seems to only happen on STM32, so I updated the title of this issue.
