LD_LIBRARY_PATH suddenly doesn't work

Suddenly, without any action I remember I made, I can't debug my executable.

There was an environment variable 'LD_LIBRARY_PATH' in the executable environment variables that worked.

Now I get an error: /path/to/bin/app.bin: error while loading shared libraries: libboost_system.so.1.62.0: cannot open shared object file: No such file or directory

When I check LD_LIBRARY_PATH. the lib is in there.

Is there any way to fix / reset it?

I'm using last official version (2016.3.2).

It also didn't work on last EAP version.

Thanks

-------------------------- update

It works and run for 'shift + F10' (run mode).

But doesn't work for 'shift + F9' (debug mode).
