I guess I only see it very rarely because I'm so used to the GNAT
command line that I don't make mistakes like gnatchop -h very often. But
it's very annoying when it happens (esp. when the machine frezes while
the program tramples over the whole address space before hitting the
SEGV!)

I see that page, but I don't see what made you try
--with-host-libstdcxx=-lstdc++! Will maybe do a 4.9.1 with this change.
