You probably won't believe it at this point. But I'm really trying to help you.

I don't understand why you would try to compile with address sanitizer flags if 
you want to find the cause of a segfault (not a memory leak!).

Please, read again the first mail that I sent you on Saturday. It contains step 
by step instructions on how to build Octave for Windows including debug symbols.

Anyway, I still think it would be best if you first create a backtrace with the 
Octave that you have already installed...
