                    cp/module.cc:6127
           Product: gcc
           Version: 12.2.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3

Created attachment 53639
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=53639&action=edit
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
