It appears to be possible to work around that issue by placing the calling convention specifier between the base type and the * (or even by placing it between extern and the base type), but we should support the proper order as well. This issue has been found by Alexander Lisachenko. Test script: --------------- <?php $ffi = FFI::cdef( 'char * __cdecl get_zend_version(void);', 'php7_debug.dll' ); echo FFI::string($ffi->get_zend_version()); Expected result: ---------------- Zend Engine v3.4.0-dev, Copyright (c) Zend Technologies Actual result: -------------- Fatal error: Uncaught FFI\ParserException: unexpected '__cdecl' at line 1 in %s:4 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=78714&edit=1
