My suggested approach:

Use the .map files to track down exactly what function that dies (and then you
can objdump them to find the exact instruction). Then re-run gcc to do
assembly output (using -S -fverbose-asm perhaps) for the files with both the
old and the new gcc and compare the outputs. Hopefully that can offer some
clues.
