描述
Description
Encountered an access violation bug in PHP 8.2.0 while executing a foreach loop on an array. It's inside a complex PHP application. Unfortunateley, I cannot reproduce the error with a small extract of the code just with the loop. Using the extract, it works :-\
I added the extract also to here. But, might not help much as it works. I assigned the variables for the loop with the same values just before the loop which crashes. Background: Application is a house automation server. Loop creates the commands for an i2c command.
What I see:
- The loop just stops before all array elements are executed and PHP exits immediately without calling any error- or exit-handler. The last command in the loop is executed. The next element is not retrieved. The loop is successfully executed ~10 times. In the next attempt, PHP crashes
- No message is written to the prompt
- No entry in the PHP error log is created (all error reporting is enabled)
- A windows access violation event is created. See attachment (partly in German; hope thats not a problem)
- It workes without errors in PHP 8.1.13 (cli) (built: Nov 22 2022 15:49:14) (ZTS Visual C++ 2019 x64)
If I can provide more information, just advise me.

调研方向
先检查 PHP_8.2.0_Crash_php.txt 和 PHP_8.2.0_Crash.txt,然后在 Windows 上使用 PHP 8.2.0 和 8.1.13 运行所提供的 extract,以确认差异。要取得进展,必须将复杂的 foreach 失败缩减为可复现的案例;完成的标准是能够复现访问冲突,并确定其原因或修复方法。
