I am not familiar with lldb, in case next command doesn't work, then maybe you can get gdb and use it on your system ... so I need the output for the next command in gdb:
``` p *( (struct qm_frag*) ( ((char*)(0x801544380)-sizeof(struct qm_frag_end)) - ((struct qm_frag_end*)((char*)(0x801544380)-sizeof(struct qm_frag_end)))->size - sizeof(struct qm_frag) ) ) ```
