That delta script had a typo (was using gcc.o instead of gccmy.o), thus the
resulting preprocessed file is irrelevant.

Here is an actually reduced testcase:

rm -f pr51648-1.gcda pr51648-2.gcda
./cc1 -fpreprocessed -quiet -g -O2 -fexceptions -fprofile-generate \
  pr51648-1.c -o pr51648-1.s
./xgcc -B ./ -o pr51648 -fprofile-generate pr51648-1.s pr51648-2.c
./pr51648
./cc1 -fpreprocessed -quiet -g -O2 -fexceptions -fprofile-use \
  pr51648-1.c -o pr51648-2.s
gives:
pr51648-1.c: In function ‘main’:
pr51648-1.c:37:1: error: corrupted profile info: profile data is not
flow-consistent
pr51648-1.c:37:1: error: corrupted profile info: number of executions for edge
4-5 thought to be 1
pr51648-1.c:37:1: error: corrupted profile info: number of executions for edge
4-9 thought to be -1

I'll attach the two sources.
