5.1 arm-64和x86-64平台调用addPatch()时崩溃

问题定位到执行方法
replace_5_1(JNIEnv\* env, jobject src, jobject dest)
dmeth->declaring_class_->class_loader_ =smeth->declaring_class_->class_loader_; 时会崩溃

Fatal signal 11 (SIGSEGV), code 1, fault addr 0x8000112cbc010 in tid 31274

Start by reproducing the SIGSEGV on both arm64 and x86-64 while tracing replace_5_1(JNIEnv* env, jobject src, jobject dest), especially the dmeth->declaring_class_->class_loader_ assignment. Investigate the platform-specific crash details and confirm the change prevents the reported failure on both architectures.
