Bug ID: 105098
Summary: ICE: endless recursion during auto deduction
Product: gcc
Version: 11.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: a3at.mail at gmail dot com
Target Milestone: ---
Created attachment 52711
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=52711&action=edit
original cpp code
While switching to libcxx from llvm-14 (actually llvm-13 fails too), using
tuple w/o explicitly passing types leads to ICE with gcc-11.2 (gcc-12 works
fine).
Note, that you can reproduce this with simple usage of tuple from libcxx 13+,
i.e.:
# /usr/include/c++/v1 - path to libcxx
g++ -std=gnu++20 -c -o /dev/null -isystem /usr/include/c++/v1 -nostdinc++
libcxx-tuple.cpp
