Bug ID: 116384
Summary: [14 Regression] ICE in convert_nontype_argument, at
cp/pt.cc:7877
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: jcowgill+gcc at jcowgill dot uk
Target Milestone: ---

test.cpp
I noticed the attached test file generates an ICE on gcc-14 and in the latest
git commit (20240815). The code was reduced from a giant pile of template
metaprogramming in a codebase I work on. It works with gcc-13. Passing
-std=c++11 or -std=c++14 is required - it does not ICE with with c++17.
I bisected the issue to this commit:
f1e5bf0d83ee4da81b6317c6d7f1278fe7eaa5a0 is the first bad commit
