Mex error: "queue = 'com.apple.main-thread', stop reason = signal SIGUSR1 " Or "Unexpected Standard exception from MEX file. What() is:vector"

I am currently debugging mex files in Mac using lldb (following structions given by https://se.mathworks.com/help/matlab/matlab_external/debugging-on-mac-platforms.html#btyq9a5) and encountered the two major errors as mentioned in the title.

The mex file was compiled without error messages using command "mex -g -output zernikeMoments main.cpp" and I ran the code as zernikeMoments(bim,int32(20)) and if everything works fine, the output should be printed directly to the screen.

For the first SIGUSR1 error, the full error message I got after typing 'bt' to lldb is as following:

For the second error, I can't get extra information other than the error message given in the title as:

Unexpected Standard exception from MEX file.

What() is:vector

..

All sources codes are attached in a zip file.

Any hints about how to debug are appreciated! Thanks in advance!
