Right, forgot about that factoid.  On Windows, the Sed part is not
required, so the command is just

  addr2line -C -f -i -p -e BINDIR/EMACS-BINARY < emacs_backtrace.txt

OK, so you compile with "-O2 -gdwarf-2 -g3", the default optimization
options, and with -mtune=generic (also the default).  Things to try,
in order to better understand the scope of the problem:

  1) try removing -mtune=generic
  2) try using -O1 instead of -O2

For 1), edit src/Makefile to remove -mtune=generic from any GCC
options there, then remove src/*.o files and say "make" to rebuild.
For 2), edit src/Makefile to change -O2 to -O1, and again remove *.o
files and rebuild.  But let's first establish the exact locus of the
crashes first, without any changes in the build options.
