Bug ID: 116317
Summary: [modules] checking ICE in type_node, at
cp/module.cc:8693 on stream out
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: ppalka at gcc dot gnu.org
Target Milestone: ---
Created attachment 58889

smallish testcase
Seen while building https://github.com/tcbrindle/flux as a module:
$ g++ -std=c++20 -fmodules-ts flux.ii
flux.ii:1:8: internal compiler error: in type_node, at cp/module.cc:9088
1 | export module flux;
| ^~~~~~
gcc trunk, 14, 13 ICE (with --enable-checking=release), gcc 12 doesn't.
Bisection points to r13-1210 but that likely just triggered a latent modules
streaming issue.
The testcase could use more reduction.
