I am running WRFDA4.3/4DVAR. The program da_wrfvar.exe is always crashed with the following error message with core dump (please see log file of running 4dvar program attached).

Error in `./da_wrfvar.exe': malloc(): smallbin double linked list corrupted: 0x0000000068b65bb0

I could not fixe the problem even though I tried to use gdb to analyze the core dump file ( please see attached gdb analysis as well as namelist.input, rsl.error.0000, and rsl.out.0000 with debug information).

Thanks for any ideas and helps.
