Bug #81311 [NEW]: Segfault running test suite with JIT enabled

From: smokey101stair at gmail dot com Operating system: Windows 10 PHP version: 8.0.9 Package: JIT Bug Type: Bug Bug description:Segfault running test suite with JIT enabled Description: ------------ Getting a segfault when running a specific test in my test suite. It happens on both PHP 8.0.8 and 8.0.9, as well as Ubuntu. Unfortunately, I don't have a reduced test case, but have provided a core dump and backtrace. I was unable to reproduce in a debug build on Ubuntu, but was able to on Windows with debug symbols. VisualStudio says "execute_data->opline is nullptr". I can publish a branch with the test suite if needed.
