With prev version everything was fine.

Will you be so kind and look into this?

Maybe we should get rid of the _Pragma operator in particular because it is not used often and we cond on compiler type later anyway.

With gcc-9 in Debian experimental, everything goes well.
Yes, the use of pragma is questionable, but let's see.

So this seems to be a gcc bug, right. Then we should close this bug.

Why do you think that it is gcc bug?

@kloczek , it is not reproducible for us, so, we consider it may be a problem other than GnuPG itself, possibly, some specific build configuration parameter(s) for GCC, or something by unreleased code.
Please file a report with how to reproduce your problem.

What you mean " it is not reproducible for u"?
Did you try to use gcc 9 and you had no problems compiling gnupg or you don't have access to build env with gcc 9?
Try to google to "gcc 9 pragma" and you will find several discussions and patches done by people fixing similar issues.

BTW: fedora corp provides already free access to build envs with gcc 9 which can be easily integrated with CIs.

@gniibe already wrote: “With gcc-9 in Debian experimental, everything goes well.”

Which one version gcc 9 you've been using?
May I see gcc -v ?

For what I use, please refer:

It is a snapshot with Debian specific patches.

Your discussion would be better to do in GCC context (as a GCC bug), because it's not the issue of ours.

I'm closing this.
