    I was checking the cplex.Model after the first solve and everything was fine.

    Hi BugHunter,

    Could you give me some code which can reproduce the crash in MATLAB?

    BTW, which OS are you using? linux 32bits or 64bits or windows 32bits or 64bits?
    which version MATLAB are you using?

    Hi John,
    I am working with Windows 7, R2010a MATLAB 64 and CPLEX 12.1 64.
    The program crashes when I create the Cplex object inside the function and pass it back to the main, trying to solve the problem 2d time in the main. The file is attached. Thanks

    Thanks much for this bug report. This is a known bug that has been introduced
    with the most recent version of Matlab, and the next version of CPLEX will include
    a workaround to the problem. However, for now you will need to go back to an
    earlier version of Matlab to avoid the problem. Version 2008b is known to work
    correctly. Sorry for this inconvenience.
