我试图使用libtasn1.h中的asn1_create_element（），但它存在错误137。然而，使用相同定义和源代码的asn1_print_structure（）可以工作。

asn1_print_structure(stdout, definitions, "IEC61850.GOOSEpdu", ASN1_PRINT_ALL); //Works fine
asn1_node * goose_pdu = NULL;
result = asn1_create_element(definitions, "IEC61850.GOOSEpdu", goose_pdu); //Exits code 137

好像是越来越没有记忆了，但是不知道是什么原因。
