Bug ID: 122070
Summary: [regression] ICE in C++23 type deduction
Product: gcc
Version: 15.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: development at jordi dot vilar.cat
Target Milestone: ---
This code (https://godbolt.org/z/Mfj1jKq6f) in compiler explorer used to
compile successfully in g++ 13 and fails with an ice (segmentation fault) in
gcc 14 & 15 with -std=c++23. In -std=c++20 mode compiles ok in all recent
versions.
The issue seems to be related to return type deduction in immediate context
when the returned type needs recursion to be deduced.
