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,
