--- Comment #3 from Arseny Solokha <asolokha at gmx dot com> ---
Aha! I've just managed to reproduce it even w/ the current gcc 13 snapshot by
adding -fstack-protector-all to the list of command line arguments:
% powerpc-e300c3-linux-gnu-g++-13 -m32 -O1 -ffloat-store -fgcse
-fnon-call-exceptions -fno-forward-propagate -fno-omit-frame-pointer -c
svj3x11t.cc -fstack-protector-all
svj3x11t.cc: In static member function 'static ar p<ar(j ...), i>::as(const
int&, j ...) [with ar = void; i = q::r; j = {o}]':
svj3x11t.cc:30:65: error: missing REG_EH_REGION note at the end of bb 6
30 | static ar as(const int &p1, j...) { (*ao<i>::ap(p1))(j()...); }
