I think they fixed it in GCC 9.

Re: strange behavior of the scheduler on STM32F070
Just checking if this is still an issue with the latest GCC?

Hi,
Yes, still there... the bug is fixed in repository but it did not make it into the distribution. M0 users should stay with 5.4.1 until next GCC release.

Re: strange behavior of the scheduler on STM32F070
Hi,
I just tried 9.3.1 2020q2 and looking at generated code it seems to be fine, LR register is preserved in the function prologue, later today I will run some tests and change the preprocessor check in the repository.
The new compiler also supports Cortex-A now, which is very nice.
