--- Comment #2 from Frank Heckenbach <f.heckenb...@fh-soft.de> ---
Got a similar ICE, hopefully the same issue.
It worked without ICE with g++ 6.3.0 and 7.3.0.
g++ 9.1.0 on Linux 4.14.0-0.bpo.3-amd64
Configured with: ../gcc-9.1.0/configure --prefix=/usr/local --disable-multilib
% g++-9 ice.cpp
ice.cpp: In function 'auto foo(bool, c)':
ice.cpp:9:24: internal compiler error: in ocp_convert, at cp/cvt.c:766
