[Bug] SampleAsyncProducer causes core dump
Search before asking
- [X] I searched in the issues and found nothing similar.
Version
pulsar cpp client 3.5.1
Minimal reproduce step
run the example: SampleAsyncProducer.cc
What did you expect to see?
it will produce the messages
What did you see instead?
it will have the coredump
Anything else?
No response
Are you willing to submit a PR?
- [ ] I'm willing to submit a PR!
Please provide more info:
- Your OS and compiler
- How did you use the library? Installed from the official pre-built libraries or built from source? If built from source, please provide the detailed steps.
The OS isTencentOS developed based on centos I use the official pre-built libraries and my compiler is g++8.5.0 If I want to compile successfully, I must add compilation options --copt=-D_GLIBCXX_USE_CXX11_ABI=0 then this will result in coredump,when call the callback of sendAsync
Oh, this issue can be reproduced. Assigned it to me first.

It seems to be the libstdc++ incompatibility in GCC 4.8.
It should already be fixed by https://github.com/apache/pulsar-client-cpp/pull/428. Could you try the RPM packages in https://github.com/BewareMyPower/pulsar-client-cpp/actions/runs/9535942883
Oh, I use the new pre-built libraries you gave https://github.com/BewareMyPower/pulsar-client-cpp/actions/runs/9535942883 When I run this program a core dump

Here are my compilation options:

It's suspicious about the path external/protobuf_archive/src/google/protobuf/message_lite.cc. The library was built via vcpkg and I cannot find any directory named protobuf_archive. Could you check the link paths of the dynamic library and the executable via ldd?
BTW, could you try building in release mode?
I can build in release mode,but the same error occurs when it runs the ldd:

it looks relatively normal
This binary links so many unrelated dynamic libraries. Most of them are from libcurl and OpenSSL.
Which library did you use? Currently, it would be better to link libpulsar.so or libpulsarwithdeps.a. It seems that you're using libpulsar.a and link to 3rd party dependencies from your system.
Besides, what is your compiler toolchain? Generally, if you're building directly via g++ like the guide here, it should work.
I use libpulsar.so from https://github.com/BewareMyPower/pulsar-client-cpp/actions/runs/9535942883,
It doesn't work just when I switch the version of libpulsar.so from 3.5.1 to 3.6.0.
And , i can work directly via g++ but can not wort when i use bazel(I use the default compiler toolchain)
Could it be that the bazel external dependency and libpulsar.so use different versions of external/protobuf_archive/src/google/protobuf/message_lite.cc?
Could it be that the bazel external dependency and libpulsar.so use different versions of external/protobuf_archive/src/google/protobuf/message_lite.cc?
Yeah it's right. So I believe it's something wrong with your Bazel project. I have experiences with Bazel a few years ago. Could you share a minimum reproducible Bazel project?
why the lib/Commands.cc include <pulsar/Version.h> ，but There is no such file I can't compile this source code
