Actually PHP Version: 5.5.11 <could be any more recent version>

Event: NULL_CLASS_PTR_READ  0xc0000005 in php_curl.dll

OS: Windows 8.0 and 8.1

Stack traces of user-mode application crashes on Windows can (with user consent) be reported to Microsoft (see Windows Error Reporting and Watson). This bug is based on one of those reports.

Watson #73434608148

Actual result:
NOTE: `aaaaaaaa` indicates NULL, indicates either stack corruption or some frames missing due to dump -> minidump conversion
