[Wien] Reg: error in Lapw2

[Swetarekha Ram]

Dear Prof.  Peter Blaha and Wien2k Users,

      I am running the WIEN2k for the position optimization. When I am
using the command run_lapw -fc 1, after some iteration (nearly after
10 cycle) I am getting error like

forrtl: severe (174): SIGSEGV, segmentation fault occurred

Can any one give suggestion to correct this error.
