See T6310 and the release note update at T6303.

Sorry, you need to wait for gnupg 2.3.8. It's next on our shortlist.

Should be fixed.

The patch for T5834 (https://dev.gnupg.org/rMad3aabdd8a64156c7e3a75d695ae1ab2c4bec841) was already applied to the build of GPGME 1.17.0 for Focal, as I did browse the list of latest GPGME bugs first before reporting this bug. Attempting to build with the latest GPGME 1.17.1 (with the included ABI patch) results in exactly the same FTBFS for i386 only, so this does appear to be a distinct issue not related to that of ABI backwards compatibility.

Please see T5834 which is fixed in 1.17.1

Please see T5587

to explain a bit more: This report was opened after the reported defect was already fixed.
As we are getting many reports and technical suggestions, please keep the reports focused on one point only if possible
and open general discussion points about development improvements on gnupg-devel@.

For what it is worth we have also just tasked someone from our team to reinstate our buildbot / CI but this would likely not have helped in the current case of the libgcrypt buffer error as only ASAN with large hashtests would have found this. Still we have the general infrastructure for such tests we are just lacking resources. That is why we publish everything and encourage the community to at least help us with testing.

the issue regarding this self test was immediately found after release. Our development is completely open and everyone is free to run tests with our software on any platform at any time. We would respect and fix all those bug reports. None about this reached us during the development phase.
As this is not happening as it should during development we release and test on our platforms and build systems. When after the release others test, too we immediately fix the issues as happened with 1.9.1 in libgcrypt.

@hanno, this is a bug tracker and not yet another media for your rants.

See the release info over at T5052 which notes the problem. See T5140 for details and update to 2.2.25.

It has been fixed in the repo for nearly a year, see T4459. A new release is urgently required and will follow in the next days. I close this as a duplicate.

2.1 has the option --unwrap to just this.

We fixed this bug already in the repo. See T4459.
