Fixes for

s. The zend_fcall_info no_separation flag has been removed, and separation is
never allowed. If you wish to pass (or allow passing) arguments by
reference, explicitly create those arguments as references using
ZEND_MAKE_REF. This removal also affects call_user_function_ex(), which
should be replaced by call_user_function().

• https://github.com/php/php-src/blob/master/Zend/zend_compile.h#L735

extern ZEND_API zend_op_array *(*zend_compile_string)(zval *source_string, const char *filename);

Curl changed return type to return object instead of resource, that's why test failed

[andypost]

@longxinH thank you for merging, I still found no way to fix curl

[andypost]

The related change is php/php-src#5402

[longxinH]

@andypost Thank you, is there any other solution I try

[andypost]

I used to run the test to try get object but stuck at this line https://github.com/longxinH/xhprof/blob/master/extension/xhprof.c#L1519-L1520

make NO_INTERACTION=1 REPORT_EXIT_STATUS=1 test \
    PHP_TEST_SHARED_EXTENSIONS="-d extension=/usr/lib/php8/modules/curl.so -d extension=modules/xhprof.so" \
    TESTS=tests/xhprof_012_8.phpt

It just type 8 (object) in 8+ so after #44 makes sense to create new release)
