[gmx-users] ambconv: Segmentation fault

[Sichun Yang]

Hi-

I'm a new user of ambconv. I have the following the error message:
AMBCONV v1.0
AMBER .top               : old.prmtop
GROMACS .top             : new.top
AMBER .rst               : nowater.rst
GROMACS .gro             : new.gro
PDB .pdb                 : temp.pdb
Segmentation fault (core dumped)

The command I used was: 
ambconv -v -at old.prmtop -gt new.top  -rst nowater.rst  -gro new.gro -pdb
temp.pdb

I've followed the email-list and patch the changes, such as
s_atop* atop = (s_atop*) xmalloc(sizeof(s_atop));
#anything#_filename = (char*) malloc(strlen(argv[i+1])*sizeof(char)+1);
fprintf(grotop, "  %6d%6d%s%12.5f%12.0f%s", ++atom1, ++atom2, "   1", 
bl, bfc,".");

Any suggestion is welcome.

Thanks,
