Output of compiler due to option -freport-bug
Environment: openSUSE 15.3 linux system.
I downloaded fmt::format from https://github.com/fmtlib/fmt/ and tried to
compile the header file fmt/core.h of this package with
g++ -freport-bug -fmodules-ts -std=c++20 -c -x c++-system-header fmt/core.h
The output of the compiler is
/usr/local/include/fmt/core.h: internal compiler error: in core_vals, at
