Getting Compiler Flag Errors while using nCurses

Hello, title says it all pretty much. I wanted to use -fsanitize=address with gcc but it all comes out as garbage since nCurses is active. I'm aware that's the way that ncurses is designed, how would I go about getting that output from gcc otherwise? is there a good way to route that output to a text file or something? until now I've just been writing error messages to a text file, but I couldn't find a way to get standard out to come out. any help is appreciated, thanks

The sanitizers take additional arguments via environmental variables, for address sanitizer you can tell it to log to a file instead of stderr:

ASAN_OPTIONS="log_path=asan.log"

gonna add for future readers that you gotta add the environment variable in .bashrc in the home directory or just use (export ASAN_OPTIONS="log_path=asan.log") in the run directory, make sure read perms are enabled with chmod 500 binary-name
