Subject: [AMBER] Vacuum simulation problem

Dear AMBER community,

I’m really puzzled by a segmentation fault error I’m getting for simply trying to do a vacuum minimization. Below is my input file and command. Note that it works fine with SANDER, but crashes with PMEMD. No error message is printed by PMEMD to the end of the out file (see below for output).

Input:

&cntrl
  ig=-1,
  imin=1, ntmin=2, ncyc=1000, maxcyc=1000,
  ntb=0, igb=0, cut=9999,
  ntc=2, ntf=1,
  ntr=0, nmropt=0,
  ntwr=100, ntwx=100, ntpr=100,
  ntxo=2, ioutfm=1,
/

pmemd -O -i min.in -p BeforeState_vac.parm7 -c BeforeState_vac.rst7 -o min.out -r min.rst7 -inf min.info


Output to terminal:

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

Backtrace for this error:
#0 0x2b2ae3e583ff in ???

What is going wrong? What should I check?
