Just tested with plain bootstrap-lto, and it gets the same failure:
../../gcc-trunk/gcc/cfg.c: In function
‘scale_bbs_frequencies_gcov_type(basic_block_def**, int, long, long)’:
../../gcc-trunk/gcc/cfg.c:945:8: error: ‘e’ may be used uninitialized in this
function [-Werror=maybe-uninitialized]
edge e;
