--- Comment #1 from Ian Lance Taylor <ian at airs dot com> 2011-08-24 17:59:14 UTC --- I haven't been able to recreate this crash yet. According to the backtrace the crash occurs the very first time a value is added to Integer_type::named_integer_types, which is a std::map. The backtrace seems to show that the code is trying to decrement a variable set to end(), which crashes because the map is empty. I don't know why this is happening. With the information I have so far it does not seem to be Go related.
