I can provide the coredump too (but it's > 200MB).

The segmentation faults only happen when using the compiled version of the library; if I include the library with Composer it's fine (but slow)

I opened the issue on the protocol buffer Forum, but they said it's an issue with Google APIs and not with their library:

https://github.com/protocolbuffers/protobuf/issues/10113

Do you have any advice?

This is happening with the most recent versions fo the libraries too.

Thank you

Hi Tommy,

Thank you for reaching out.

I would suggest referring to this document as it discusses all the processes on how to configure the PHP client library including about the protobuf PHP Extension that can be seen on this document.

Let me know if you have further questions.

Thanks,

Hi Nirmita,

  thank you for your quick reaction.

The php compiled extension is compiled and installed properly.

I use:

pecl install protobuf

I can properly download reports, but every once in a while php crashes with a segmentation fault.

I'm not sure this was clear, the links that you kindly provided are meant for people installing it the first time, I guess.

Thank you

Hi Nirmita,

Are you asking me to contact the team that has developed the Google Ads php client library?

Thank you
