Found a patch that fixes this bug, not sure if it's correct. The problem is the compile_for_eval is always 1 (coming from the th->parse_in_eval flag.) The parse_in_eval is incremented in the process_options function, not sure why. I tried to change the value and things broke in a most horrible manor.

Found a quick fix that seems to work correctly, just removed the check for compile_in_eval. The check for debug_lines seems to do the right thing. Not sure if this is a help, just trying to be useful. ;-)

Hope this helps,
