"Fatal Error Unable to reattach to base address" while running in cmd and PowerShell

[mjordan]

When running background commands (here is my code) in Windows PowerShell or cmd shell, the command fails and the error Fatal Error Unable to reattach to base address is printed to STDOUT. This doesn't happen when running the same code under Git Bash, where the commands execute as intended. A typical command that I am running is "php m:\mik_mark\extras\scripts\postwritehooks\validate_mods.php", with some arguments to the validate_mods.php script added at runtime.

A quick google for that error brings back some issues surrounding Zend Opcache (like this one).

Has anyone seen this before or have any suggestions as to how work around it? I'm on Windows 7 Enterprise SP1 (64 bit). php -v produces:

I've found a fix, or at least a way of avoiding the issue: commenting out opcache.enable_cli=1 in php.ini.
