Summary0001897: Crash when removing a breakpoint
Description

Hello,

xdebug 3.0.0, PHP 7.4 on macOS. Step debugging works great, but if I remove a breakpoint during the debugging-session the php process dies. It does not depend on the script. It breaks on every script, even very simple ones. See the attachment. I use PhpStorm 2020.2.4 as IDE/Client.

Error message

php ./web/test.php
php(28254,0x112819e00) malloc: error for object 0x6000000000000000: pointer being freed was not allocated
php(28254,0x112819e00) malloc: set a breakpoint in malloc_error_break to debug
[1] 28254 abort php ./web/test.php

Steps To Reproduce
  • Enable xdebug in PHPStorm
  • Set breakpoint on Line 2 ($a)
  • php test.php
  • Breakpoint is triggered
  • Step one line further
  • Remove breakpoint in PhpStorm
  • php dies

I did a test with Xdebug for VSCode https://marketplace.visualstudio.com/items?itemName=felixfbecker.php-debug. Same problem.

Thanks!

Would you mind adding a log file through the xdebug.log setting? See https://xdebug.org/docs/all_settings#log
