Regression: changes in descriptor_databases (?) break codegen check in protobuf-c with Bus error #24158
Description
What version of protobuf and what language are you using?
protobuf 33.0
protobuf-c 1.5.2
Language: C++
What operating system (Linux, Windows, ...) and version?
macOS 10.6.8 / ppc
(Yeah, I know this is an “exotic environment”, but this is C++, there is no reason it should fail, especially given that an earlier version worked.)
What runtime / compiler are you using (e.g., python version or gcc version)
gcc 14.3.0 / libstdc++ runtime
What did you do?
Install protobuf 33.0, try building protobuf-c 1.5.2 with it.
What did you expect to see
protobuf-c 1.5.2 has built fine with protobuf 30.2. The same version should continue to build successfully.
What did you see instead?
It does not build with protobuf 33.0. A crash happens on test_unknown_fields: https://github.com/protobuf-c/protobuf-c/blob/4719fdd7760624388c2c5b9d6759eb6a47490626/t/generated-code2/cxx-generate-packed-data.cc#L998-L1089
