I am looking into a core from 64 bit system. Architecture is set correctly but still pointer value is printed as 4 bytes. What changes are needed to make it print 64 bit value ?

(gdb) p sizeof(void *) $16 = 8 (gdb) p this $15 = 0x4852200 (gdb) show architecture The target architecture is assumed to be i386:x86-64:intel

What changes are needed to make it print 64 bit value

GDB is already printing 64-bit value. It just so happens that the upper bits are 0.
