Hi:

Tried Jonny Grant's example
g++ -O3 --std=c++23 -Wall -c repro_jg01.cc

With the mainline build, the code compiles without any error.

Environment
- Linux  6.1.0-3-amd64 x86_64 GNU/Linux
- Debian GLIBC 2.36-8) 2.36
- gcc version 13.0.1 20230215 (experimental) (GCC)

Curious to know, what changed in the mainline code ? Anyone knows the commit hash ?


warm regards
Saifi.
