Errorlevel -1 compiled exe (R2016a)

Hello,

I compiled a matlab script with 2016a into an exe-file a start several of them in parallel using a bat-script in that I use

 start /WAIT compiledprog.exe

The errorlevel is -1 from time to time... most time everything, so algorithm in the compildprog.exe seems fine... so I assume that there is a somehow a problem with the matlab runtime, memory, or I don't know

my whole matlab-function has a try-catch block, where I force the program to give a specific exit-value unequal to -1 ... therefore I wonder to get -1 as error level?

Is -1 any know obvious problem with the matlab runtime? or memory? is somewhere a list for the errorcode/errorlevel? or what infos could I provide to get more information about the source of error?

Thank you

Andreas, can you provide the sample reproduction code and a screenshot of the error message you receive?
