gcc.i
/some/path/gcc/cc1 -fpreprocessed -quiet -quiet -dumpbase gcc.c -mtune=generic
-march=x86-64 -g -O2 -fexceptions -fstack-protector -fprofile-use --param
ssp-buffer-size=4 /tmp/gcc.i -o /tmp/gcc.s
reproduces this with the attached gcc.i and gcc.gcda. Of course the problem
might be already at the -fprofile-generate phase or at runtime when generating
the gcc.gcda file.
