I added two new functions and don't know why I get a segfault when invoking scard_begin_transaction()...

I am not that deep into PECL extension debugging so I can not figure out what is going wrong.

When running ./docs/examples/simple.php I get a segmentation fault when executing the script on line 647 in pcsc.c:

ZEND_FETCH_RESOURCE(hCard, SCARDHANDLE, &conn_res, -1, PHP_PCSC_CONN_RES_NAME, le_pcsc_conn_res);

GDB gives me this:

Program received signal SIGSEGV, Segmentation fault.
0x00007ffff4b1c611 in zif_scard_begin_transaction (execute_data=0x7ffff52136d0, return_value=0x7ffff5213370)
at /home/hanez/code/pcsc-for-php/pcsc/pcsc.c:647
647 ZEND_FETCH_RESOURCE(hCard, SCARDHANDLE, &conn_res, -1, PHP_PCSC_CONN_RES_NAME, le_pcsc_conn_res);

I believe I did everything right but it seems I didn't... :(

Can someone explain what is wrong or give me some hints how to debug this?

Git head gives these errors at the moment:

Stop.

I had to regenerate the arginfo header files.

I switched to PHP 8.0.3 today for testing but it seems that the extension is not working there. In 7.4.16 everything works as expected. Does someone have an idea what could be wrong here?
