Bug ID: 113580
Summary: -Wunused-parameter in template imported from module
causes segmentation fault
Product: gcc
Version: 13.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: michael.kenzel at gmail dot com

export void fun(auto&& x) {}
// main.cpp
import A;
int main()
{
fun(42);
}
g++ -std=c++23 -fmodules-ts -c -x c++ A.ixx
g++ -std=c++23 -Wunused-parameter -fmodules-ts main.cpp A.o
results in
Segmentation fault

c++: Stream additional fields for DECL_STRUCT_FUNCTION [PR113580]
Currently the DECL_STRUCT_FUNCTION for a declaration is always
reconstructed from scratch. This causes issues though, as some fields
used by other parts of the compiler (in this case, specifically
'function_{start,end}_locus') are then not correctly initialised. This
patch makes sure that these fields are also read and written.
PR c++/113580
gcc/cp/ChangeLog:
* module.cc (struct post_process_data): Create.
(trees_in::post_decls): Use.
(trees_in::post_process): Return entire vector at once.
Change overload to take post_process_data instead of tree.
(trees_out::write_function_def): Write needed flags from
DECL_STRUCT_FUNCTION.
(trees_in::read_function_def): Read them and pass to
post_process.
(module_state::read_cluster): Write flags into cfun.
gcc/testsuite/ChangeLog:
* g++.dg/modules/pr113580_a.C: New test.
* g++.dg/modules/pr113580_b.C: New test.
