Gdb to a particular code, suddenly out of this suggested : 0x0000000010007f38 in. _ZN18CRecordProcess_CDR4initEv () At /usr/include/c++/3.2.3/new:88 Then the show became such a LINUX : 88 4003rd Default placement versions of operator new. (Gdb) 0x0000000010007f3c 88 4003rd Default placement versions of operator new. (Gdb) 0x0000000010007f40 88 4003rd Default placement versions of operator new. Who knows how else is? Thank you ~ ~
