[gmx-users] Error with gmx dielectric

[Roberto Olmi]

Dear All,

before sending a post to gmx-developers, I would like to know if someone else has my same problem.

When executing "gmx dielectric …." on a simulation, after having produced the dipole correlation file with "gmx dipoles -corr total -P 2 ….", I get the following error:

*** Error in `gmx': malloc(): smallbin double linked list corrupted: 0x000000000078b730 ***

If I reduce the size of dipcorr.xvg, including only a short time duration, the error disappears (but, of course, the solution is not correct due to the time cut). 

I have seen that this kind of problem has sometimes been reported in the lists, but without a solution. I have also tried to recompile GROMACS with debugging ON, but I think this is not a topic for the users list.

Am I the only one having that problem? I use GROMACS under Ubuntu linux.

Thanks,
Roberto
