Bug ID: 106848 Summary: ICE when compiling module interface file with -g: error: type variant differs by TYPE_MAX_VALUE Product: gcc Version: 13.0 Status: UNCONFIRMED Keywords: ice-on-valid-code Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: redi at gcc dot gnu.org Blocks: 103524 Target Milestone: --- $ cat std.cc export module std; import <bits/stdc++.h>; Compiling the bits/stdc++.h works OK: $ gcc -c -std=c++23 -fmodules-ts -x c++-system-header bits/stdc++.h And compiling the module file works without -g: $ ~/gcc/13/bin/gcc -c -std=c++23 -fmodules-ts std.cc But with -g there's an ICE: $ ~/gcc/13/bin/gcc -c -std=c++23 -fmodules-ts std.cc -g std.cc:3:24: error: type variant differs by TYPE_MAX_VALUE 3 | import <bits/stdc++.h>;
