Trivial fixes like this should be installed at the same time on branches.

Is there a chance this will be backported to 4.5? As Jakub pointed out at
PR44178/comment #7, gcc 4.5 r160526 (with RTL checking) fails on this testcase
with:
$ gcc -fsched-pressure -fschedule-insns pr43332/testcase.c

I have just finished bootstrap of r160198 with valgrind checking, the problem
is no longer reproducible there. I am sorry for the delay, make check with
valgrind checking takes about a month there (1.3GHz), bootstrap about

Thanks for reporting the problem. The problem has no effect on generated
code whatever initialization is used. The code in question tries to get basic
block for BARRIER which is wrong. Whatever it gets basic block

Thank you for fixing this. I hope to rebuild gcc with valgrind checking in few
days again.

Stil appears in r159500, x86_64-linux.
Uninitialised read is at gcc/haifa-sched.c:1589, more exactly it is read of
BLOCK_FOR_INSN (insn)
When gcc/haifa-sched.c:1589 is changed to:
insn != NULL_RTX (printf(%p %p\n, (void

Thank you for feedback. However, this happens in r157335, so it's not fixed by
that patch. It's only reproducible with valgrind checking because
ggc_alloc_stat() uses VALGRIND_DISCARD which is a no-op in other cases. When

It is the same and was fixed by the same patch.
