The reason probably is in a buggy _get_osfhandle() function that doesn't return proper HANDLES for standard system streams. We need find out a workaround for this problem. the bug is probably related to bug #7960 Reproduce code: --------------- <?php $f = fopen("php://stdout", "w+"); fwrite($f, "Hello\n"); ?> Expected result: ---------------- Hello Actual result: -------------- Crash with the following stack trace NTDLL! 7c90eb74() NTDLL! 7c90eb94() _php_stream_fopen_from_fd(int 0, const char * 0x00416fb0 `string', const char * 0x00000000, int 0, char * 0x1070a25c `string', unsigned int 246, char * 0x00000000, unsigned int 0, void * * * 0x02714fe0) line 200 + 24 bytes php_stream_url_wrap_php(_php_stream_wrapper * 0x108a5d28 _php_stream_php_wrapper, char * 0x00416fa6, char * 0x00416fb0 `string', int 8, char * * 0x00000000, _php_stream_context * 0x00000000, int 1, char * 0x106dd51c `string', unsigned int 1774, char * 0x004165c8 `string', unsigned int 498, void * * * 0x02714fe0) line 246 + 41 bytes _php_stream_open_wrapper_ex(char * 0x00416fa0 `string', char * 0x00416fb0 `string', int 0, char * * 0x00000000, _php_stream_context * 0x00000000, int 0, char * 0x004165c8 `string', unsigned int 498, char * 0x00000000, unsigned int 0, void * * * 0x02714fe0) line 1774 + 111 bytes cli_register_file_handles(void * * * 0x02714fe0) line 498 + 52 bytes main(int 2, char * * 0x026f8fc0) line 1030 + 12 bytes ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=38488&edit=1
