Sorry, you were right, --with-pic works, it was my mistake.

I am sorry, I don't understand how that comment helps. Could you explain
a bit further, what needs to be done to make the build work again?
configure --with-pic does not help to solve the problem.

I do not. I just compile PHP. The script used to configure and build it
is here:
https://github.com/google/oss-fuzz/blob/master/projects/php/build.sh
There are no special flags there as far as I can see. The fuzzing SAPI
lives here: https://github.com/php/php-fuzzing-sapi
The compiler used is clang. You can reproduce the build by using Docker
and these instructions:
https://google.github.io/oss-fuzz/getting-started/new-project-guide/#testing-locally

Specifically:
python infra/helper.py build_image php
python infra/helper.py build_fuzzers --sanitizer address php
or, if you want to see the details, instead of second command, use:
python infra/helper.py shell php
and then:
compile

I added --with-pic, it didn't change anything, same error.
