MATLAB crashed when running the .mexw64 file

when i running the program，which include .mexw64 function. Everytime running to the row of function using .mexw64, my matlab crashed and the log file is as follows:

This error was detected while a MEX-file was running. If the MEX-file

is not an official MathWorks function, please examine its source code

for errors. Please consult the External Interfaces Guide for information

on debugging MEX-files.

How was demod.mexw64 created? Who is the author? Is it a C-Mex function?

[Eric Pu]

demod.mexw64 is created by command "mex demod.cpp", and the demod.cpp's author is not me. And It is a C-Mex function.

I have installed the MinGW-w64 C/C++ Compiler, and mex the demod.cpp again. But it didn't works.

[Eric Pu]

Thank you for your reply.

[Jan]

Then the code of demod.cpp contains a bug, obviously. It is very easy to let a C or CPP code crash tremendously.

You have to debug this code. Maybe you want to post it here, but then please try to locate the failing line at first.

[Eric Pu]

thanks for your suggestion. but when i run the program in matlab2016a，it success and the matlab did not crash.

[Jan]

Yes, this is possible. Maybe the compiler you have used for the older versions, used UINT32 for addressing and now it is size_t?

There are many ways to kill a C-mex function by an access violoation. Dangling pointers can cause not reproducible crashes also: If some memory is free'd already, it might still have the correct value. But this can change for random reasons. In opposite to Matlab, C and C++ is fragile. If a function does not crash 100'000 times, this is still not a reliable statement if it is free of bugs, which will let it crash in the next call.

[Eric Pu]

Thank u！I‘ll check the C code firstly, and then test the program.’

Answer 1

[Eric Pu]

I had solved this problem, the reason is the error about the input parameter. One of hte program's input parameters should be a complex number, but the input number is double type. So it does not have imaginary part, and caused the crash of matlab.

Answer 2

[Anirban]

Is it this issue: https://www.mathworks.com/help/bugfinder/ug/fix-matlab-crashes-polyspace-in-matlabroot.html ?

[Eric Pu]

thanks for your reply, but maybe it is not this issue.

Answer 3

[Image Analyst]

The last file it mentions before the final gasp and death is "D:\matlab_files\yuhengv2\LLS-NR-pattern\11_demodulation\demod.mexw64". Are you sure that file exists?

[Eric Pu]

yes, actually i created this file in the folder
