Bug ID: 116565
Summary: ICE in tsubst, at cp/pt.cc:16401
Product: gcc
Version: 14.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: tsnorri at iki dot fi
Target Milestone: ---
Created attachment 59038
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=59038&action=edit
Compiler input
Attached is the input processed with cvise. I used GCC 13 to preprocess the
original input in order to get valid code for it as well as GCC 14.
Command line:

Triggered with following versions:
g++-14 (Homebrew GCC 14.2.0) 14.2.0 (both GNU/Linux on x86_64 and macOS on
arm64)
g++ (conda-forge gcc 14.1.0-1) 14.1.0 (tested GNU/Linux only)
Not triggered with any of the following on either platform:
g++-13 (Homebrew GCC 13.3.0) 13.3.0
g++-12 (Homebrew GCC 12.4.0) 12.4.0
(Unfortunately I don't have access to GCC 14 installed with the operating
system's package manager.)
Configuration options for the GCC 14 builds tested on Linux:
g++-14 -v
