Hi Mark,

thanks for your work on that issue. I have some spare time today and will try some combinations
about NO INVARIANTS and so on. My src.conf is the following,

---------------------------
WITH_MALLOC_PRODUCTION=1
WITH_EXTRA_TCP_STACKS=1
WITH_BEARSSL=1
WITH_PIE=1
WITH_RETPOLINE=1
WITHOUT_CLEAN=1
---------------------------

I know that the change itselfs doesn't seems to be significant, but it was the
first that has triggered the panic. Maybe it is also the u-boot.bin, I haven't
updated them since the July.

I'll keep you posted.
