Invalid character in include file hangs Lazarus on opening project

Original Reporter info from Mantis: BigChimp

Reporter name: Reinier Olislagers

Description:

When opening the attached project with invalid data (character "'ÿ'" ($FF))(where I accidentally typed {$i fclel.res} instead of {$r fclel.res}, Lazarus hangs and does not respond.

Running lazbuild hangs after reading the config file. (Note: tried with a simple GUI application which did show an error running lazbuild)

Steps to reproduce:

Try to open or compile attached console project.

Additional information:

Compiling with fpc does give a useful error message:
