A r131535 of trunk bootstrapped with --enable-langugages=c
--enable-checking=release,valgrind shows this indication for several
test-cases, the first being tmpdir-gcc.dg-struct-layout-1/t001
c_compat_x_tst.o compile
(just the first indication of several identical is shown):
Executing on host: /tmp/hptest8/obj/gcc/xgcc -B/tmp/hptest8/obj/gcc/ -w
-I/tmp/hptest8/gcc/gcc/testsuite/gcc.dg/compat -fno-show
-column -c -o c_compat_x_tst.o
/tmp/hptest8/obj/gcc/testsuite/gcc/gcc.dg-struct-layout-1//t001_x.c (timeout
= 300)

It was later reported as PR/38781 and fixed.
No valgrind errors here with r146637.
