我有一個堆棧跟蹤,看起來像這樣:gdb堆棧跟蹤的第二列是什麼意思?
#3 0x00007fffde86c206 in GetMedia (p_ml=0xb91560, id=<value optimized out>, select=ML_MEDIA, reload=<value optimized out>) at ../../../modules/media_library/sql_media_library.c:1170
#4 0x00007fffde86a7d0 in GetInputItemFromMedia (p_ml=0xb91560, i_media=12276000) at ../../../modules/media_library/sql_media_library.c:1204
#5 0x00007ffff6765eab in ml_CreateInputItem (this=0x7784f0) at ../../../../include/vlc_media_library.h:887
#6 MLModel::popupInfo (this=0x7784f0) at ../../../../modules/gui/qt4/components/playlist/media_library/ml_model.cpp:528
#7 0x00007ffff67a7204 in MLModel::qt_metacall (this=0x7784f0, _c=<value optimized out>, _id=17710, _a=<value optimized out>) at components/playlist/media_library/ml_model.moc.cpp:79
#8 0x00007ffff4ec8e3f in QMetaObject::activate(QObject*, QMetaObject const*, int, void**)() from /usr/lib/libQtCore.so.4
我想知道的是,第二列表示。此外,它的缺乏意味着什麼?可以看出,第6幀沒有這個地址,我相信我的問題(段錯誤)是由於相關的事情而導致的。
