Re: Prothon bug: strange interaction between self and add_

1) I have added command line options to build 511 that allows you to
enable/disable debug features that used to be compile-time options.  Use -h
to see details.

Can you try running your example with -dG set?  This disables the garbage
collector.  If it still has problems let me know.  If this fixes your
problems you can run this way until I fix your bug.

2) I have dupicated your problem on my laptop.  Apparently it happens more
often on slower setups.  I will debug it there.
