When using 'sim' in a for loop in accelerator mode I get an 'accelbuild' error after 5,6 or sometimes 18 iterations.

I am doing a Monte Carlo simulation of a simulink model with Matlab 2015b using the sim command

SimOuts = sim(ModelName, 'LoadExternalInput', 'on',...
                         'ExternalInput', 'SimIns',...
                         'SimulationMode', 'accelerator');

Unfortunately, after several iterations of the model running fine, I get

Error using accelbuild (line 50)
Problem creating Accelerator MEX file for model
'my_model'.
 To see the build output, use
 set_param('my_model','AccelVerboseBuild','on')
Error in run_test_harness (line 6)
accelbuild(ModelName);
Caused by:
      Error using accelbuild (line 50)
      Unable to write file
