should not affect anything patch

Interestingly now I am running with this patch, but I never saw this code path
taken ever so it should not count.

Also I have compiled with this setup and it works still:

meson configure build/ -Dc_args="-O2 -Ofast" -Dcpp_args="-O2 -Ofast"
-Dc_link_args="-O2 -Ofast" -Dcpp_link_args="-O2 -Ofast"

I have yet to try with -O3 so far now, but it more and more looks this is just
some kind of rare heisenbug. When it is not happening I cannot even make it
work..

Also now that the bug only seem to appear very rarely it is much harder to
debug and I think its impact is much smaller too...
