value optimized out?


Hi List,


  I do not understand some of the terms produced in backtrace output
when debugged MEME(Multiple Em for Motif Elicitation, a bioinformatics
application) with GDB.

    The program terminated in between, giving Segmentation fault.

    (gdb) f 0
#0  0x0000000000410c55 in tcm_e_step (model=0x14c1490,
dataset=0x8b2030) at tcm.c:132
132               double logsum0 = LOGL_SUM(log_pXijtheta0, log_pXijtheta1);

   logsum0 = <value optimized out>
        log_pXijtheta0 = -nan(0x8000000000000)

   Can any one tell me what are:

     <value optimized out>  &
    -nan(0x8000000000000)


Regards,
