            Bug ID: 115203
           Summary: [15 Regression] Build fail with non LANG=C in analyzer
                    self test: ICE in fail_formatted at selftest.cc:63 /
                    tree-diagnostic-path.cc:2158: test_control_flow_5:
                    FAIL: ASSERT_STREQ
           Product: gcc
           Version: 15.0
            Status: UNCONFIRMED
          Keywords: build, ice-on-valid-code
          Severity: normal
          Priority: P3
         Component: analyzer
          Assignee: dmalcolm at gcc dot gnu.org
          Reporter: burnus at gcc dot gnu.org
  Target Milestone: ---

For some testing, I happened to build with LANG=de_DE.UTF-8
and that was also set when building GCC itself.

That works fine until the analyzer self test - as the strings don't match:
