Do you still get this segfault with any of the actively supported
PHP versions[1]?

Thanks for your respond.
I don't see which script is causing the problem, because I always get this output:
(gdb) print (char *)(executor_globals.function_state_ptr->function)->common.function_name
Attempt to extract a component of a value that is not a structure.

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves.
A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external
resources such as databases, etc. If the script requires a
database to demonstrate the issue, please make sure it creates
all necessary tables, stored procedures etc.
Please avoid embedding huge scripts into the report.
