That is still the way to go. It is not terribly difficult but can be overwhelming the first times. Just push yourself through after a few times it gets easier. There are some tricks to help though: - increase verbosity (-va) from this log you can sometimes find out where the crash happens - inserting errors in the relevant unit by inserting random characters in a binary search program (if the compiler errors on the "XXX" that I inserted, then that spot is before the crash, ok, now lets move the XXX a bit further into the unit) - recompiling the compiler with lineinfo (-gl, -gw, don't know if that works for win64 atm), the traceback might give you an idea which language feature causes the crash. _______________________________________________ fpc-devel maillist - [email protected] http://lists.freepascal.org/mailman/listinfo/fpc-devel
