--- Comment #4 from Chris Johns <chris at contemporary dot net.au> 2013-04-02 06:23:53 UTC --- Created attachment 29771 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=29771 xgcc dumps from a cygwin build that also fails. The file contains all the gcc trace and dump output I could figure out. If more is needed I am happy to collect it so please let me know what I need to add.
