Version:
GNU C++14 (GCC) version 8.0.1 20180306 (experimental) (x86_64-pc-linux-gnu)
Bug #83865 has the same error but it's for Fortran and the call stack is
different.
Without -O2 it gives a different error:
<source>:1:34: internal compiler error: in synthesize_implicit_template_parm,
at cp/parser.c:39031
a(decltype((0 > 1e91 && 1e31 && (auto))))
That one has multiple possibly related bugs already: #84642, #84610, #83583,
#82768, #78802, so maybe a fix for one of those will also fix this, I don't
know.
