std::bad_alloc错误

[ming-jh]

您好，请问我改成我的雷达和imu话题后，出现'std::bad_alloc'错误，这是为什么呢？数据都是同样类型的
imu data less than 0.2s, waiting for next packet
QObject::connect: Cannot queue arguments of type 'QVector'
(Make sure 'QVector' is registered using qRegisterMetaType().)

terminate called after throwing an instance of 'std::bad_alloc'
what(): std::bad_alloc

期盼回复
