Dear Quantum espresso developers and users,

I'am trying to use the lda-1/2 for the first time to correct the band gap of Sb atom, i've followed the example of Si in the atomic code, using the inupt file:

&input
       title='Sb',
       zed=51,
       config='[Kr] 5s2 5p3 4d10',
       iswitch=4
       rel=2
/
&test
  file_pseudo='Sb.pz.paw.UPF',
  file_pseudopw='Sb.lda.0.5.UPF',
  configts(1)='5s2 5p3 4d10',
  configts(2)='5s2 5p3 4d9.75',
  rcutv=1
/

after that i exexuted this script ./job.test
#!/bin/bash
workd=./results/
mkdir -p $workd
./ld1.x <Sb.lda.0.5.in > Sb.lda.0.5.out
mv *.out Sb.lda.0.5.UPF $workd
rm -f *.wfc


however i received this error:

Program received signal SIGSEGV: Segmentation fault - invalid memory reference.

Please help me  to  resolve this error, and i'll be so grateful.
