Ah. Yes, that can be a pain. The only way I've ever "fixed" this problem is hacking configure to use "-O -g" instead of "-O2 -g". > Nevertheless I did what you suggest and climbed up those 6 levels to find that > indeed expr->where has null fields.

This is definitely a bug in that expr->where should be set. Are you using OOP? > I am rebuilding with your suggested gfc_current_locus change and reporting the > results. It may simply give you nonsense, but the compiliation should continue. This may be a warning that can then be ignored.
