root-6.28.04 fails to compile with gcc-13 under linux TW

[svenmenke]

Dear all,

while root-6.28.03 compiled with the patch provided in response to issue #12659 a similar problem is back now in root-6.28.04 (retrieved via latest-stable from github today). I just did (on suse TW):

git clone --branch latest-stable --depth=1 https://github.com/root-project/root.git root_src
mkdir root_build
cd root_build
cmake ../root_src -j4

and this produced:

...

..

It's not the exact same error message as in #12659 but seems rather close in nature ...
Could you please have look if the patch from 6.28.03 needs further additions to address this in 6.28.04?

Thanks & Cheers,

sorry about the bad formatted post - I did not intend any font change nor the setting of the 'bug'-label. Apparently the copy-pasted g++ error output triggered both of these. I hope it does not distract from the actual issue that compiling fails again under g++-13.
Thanks,

Sorry about that, we were missing a backport after applying other fixes: #12901

P.S.

You can disable formatting of pasted logs by surrounding them with three backticks on individual lines. I've edited the original issue summary accordingly 😉
