Bug ID: 120961
Summary: ICE on C++20 module when compiling Eigen.
Product: gcc
Version: 15.1.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: shyeyian at petalmail dot com
Target Milestone: ---
I bumped into ICE when compiling Eigen into `C++20 module`.
The scenary is hard to reduce, but I hope it would provide more information for
maintainers to figure out the bugs in `module` feature.
Everything is in [attachment](gcc-ice-preprocessed.out).
**Thank you!**
