Hi hj,
libffi-3.4.2's new static trampoline feature is known to break some
downstream packages with some specific use (or misuse?) of libffi,
unexpected by the libffi developers. For example
https://gitlab.gnome.org/GNOME/gjs/-/issues/428.
I've not use gccgo recently, so I don't know if it might break something
here. Just a reminder, if the regtest on x86 and arm (32-bit and 64-
bit, they are the only platforms where libffi enables static trampoline)
is OK there should be no problem.
