从代码流程看是info指针或者bakMethod指针失效，gdb跟踪(ArrayObject *) info->paramTypes，发现会被memset, fork等函数修改，在主线程调用java_method_hook就无此问题

HookInfo *info = (HookInfo *) malloc(sizeof(HookInfo));
......
Method *bakMethod = (Method *) malloc(sizeof(Method));
Memcpy(bakMethod, method, sizeof(Method));
info->originalMethod = (void *) bakMethod;
......
method->insns = (u2 *) info;
......
HookInfo *info = (HookInfo *) method->insns;

pResult->l = (void *) dvmInvokeMethod(thisObject, originalMethod, argTypes,
                                      (ArrayObject *) info->paramTypes,
                                      (ClassObject *) info->returnType, true);
