I am developing an S-Function to be used in Simulink. While the block is in development, there is a lot of recompiling and I think this is causing Matlab to crash. My current workflow consists of something similar to the following:

-Modify the C/C++ source code

-Recompile with mex

-Rerun simulation diagram

Frequently, when I try to run the simulation directly after a recompile, Matlab will crash before the simulation even has a chance to start. In fact, sometimes I need not even start the simulation to trigger a crash, but simply trying to save or close the diagram after a compilation will cause the same behavior.

Any ideas or similar experiences? Thanks in advance. -Nick

OS: CentOS 7

Please post your crash log (can be found as described here: https://www.mathworks.com/matlabcentral/answers/100816-how-do-i-locate-the-crash-dump-files-generated-by-matlab ). Or better yet, submit it through the dialog that appears after the crash. If the log matches a known issue our automated system will send you a link with more information, and if not then a member of our technical support team will be able to assist you.
