Also does not reproduce with a debug compiler at r243219:

wschmidt@genoa:~/src$ $GCC_INSTALL/bin/gcc -S -O3 pr78695.c
wschmidt@genoa:~/src$ $GCC_INSTALL/bin/gcc -v

I will try a bootstrap compiler.  Can you please post your configuration, and
any possible local modifications?  This looks like something that is very
sensitive to middle-end optimization, so small changes can make the problem
disappear.
