Crash with improper hybrid style none

Hello fellow lammps-users,
in using the improper style hybrid, i get a reproducible crash as soon as i
set one improper_coeff to none.
The error is:
*** Error in 'lmp_serial': free(): invalid next size (fast):
0x000000000002915460 ***
This does not happen for dihedrals where i disable some interactions.
I reproduced this with lammps versions 23Nov13, 1Feb14 and 16Feb16, with or
without modified Makefiles,
and on different machines. All are running more or less up to date versions
of opensuse.
Any ideas? Any additional infos i can provide?
your description is not quoting the exact syntax, thus it is difficult
to make an accurate assessment.
it is usually beneficial for cases like yours to provide a minimal
(but complete) input deck that reproduces the issue.

My input is as follows:

units real
dimension 3
newton on
boundary f p f

atom_style full
read_data inpgeom
special_bonds amber

improper_style hybrid cvff
improper_coeff 1 cvff 1.1 -1 2
improper_coeff 2 none
pair_style lj/cut/coul/cut 10.0
pair_coeff 1 1 0.015000 2.600713
pair_coeff 1 2 0.035917 3.000891
pair_coeff 2 2 0.086000 3.401070

Free(): invalid next size(fast)//malloc(): memory corruption

Hello dear Rooters,

I wrote a program that finds all the hits and identifies those which overlap from data taken with an oscilloscope. In event::reduce() (event class corresponds to one file-profile and has members as vector, noise, threshold, etc, where hit is another class corresponding to a single pulse - I can attach the scripts under request) I identify the superpositions, each hit has a label member which sorts them out (same group number means pulses overlapping). Then, in analysis.cxx, the code below, I reduce all the hits. I fit the pulses overlapping and create two event branches, one with the original info (hits without fit parameters) and another one with hits with the fit parameters, a branch TMultiGraph with the graphs of the superpositions and another branch TClonesArray with TFitResult instances of the fits. Apparently everything works well when I process a group of files with only one file with a superposition (file 12 is first file with a superposition). So, when I run ./analysis.exe /eth/ethraid5/home/dnarrias/data_Daniel-Thomas/15Nov/Waveforms MI-1_687_ampl 20 RT_687_test.root, the program wor

free(): invalid next size (normal): cudaMalloc problem

Hi everyone. I have spent a large amount of time trying to figure out the problem that I am about to attempt to present, and am looking for help.

I am writing a program that is using a standalone library with its own make utility configured specifically for the library in such a way that I must use it lest I want to spend more time putting things together than writing my code. This means that I cannot use nvcc to compile everything and have to separate things. Half of my code is compiled via the custom make utility, and the other half - the cuda bit, is compiled by nvcc into a static library. The library contains a wrapper class, and the kernel that I want to run.

I compile and link everything fine, however, at runtime I get this libc6 error:

I was able to trace this problem to the cudaMalloc function inside my static library using ddd. At the end of the cudaMalloc execution I get this error. I have tried everything I can think of to resolve this, but perhaps I am missing something simple. here are the important bits of my code relating to this error:

And the wrapper function:

Any help you can provide would be MUCH
