Description

The following cmd.exe invocation:

php -r "ini_set('memory_limit', '6G'); $size = 5 * 1024 * 1024 * 1024; $str = str_repeat(\"\x00\", $size); file_put_contents('test.bin', $str);"
dir

Resulted in this output:

C:\reproduce>php -r "ini_set('memory_limit', '6G'); $size = 5 * 1024 * 1024 * 1024; $str = str_repeat(\"\x00\", $size); file_put_contents('test.bin', $str);"
PHP Notice:  file_put_contents(): Write of 4294967295 bytes failed with errno=0 No error in Command line code on line 1

C:\reproduce>dir

But I expected this output instead:

C:\reproduce>php -r "ini_set('memory_limit', '6G'); $size = 5 * 1024 * 1024 * 1024; $str = str_repeat(\"\x00\", $size); file_put_contents('test.bin', $str);"

  • tested on both 8.3.2 and 8.3.0
  • interestingly, it does /not/ reproduce on Linux.
