           Summary: bootstrap comparison failure with 174455 on OpenBSD
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: jsg@openbsd.org


bootstrap fails with revision 174455 on OpenBSD/i386 -current.
Compiled with a lightly patched GCC 4.2.1

This is a different list of object files to pr 49242 so opening a new pr.

Jonathan, are you still seeing this?  Right now FreeBSD fails similarly for
me, but until August 2nd everything was fine on that platform.

I was still seeing it about a week or so ago.  At the moment I can't even get
past stage1 however.  Something seems to go into an infinite loop around

stage 1 in i386-unknown-openbsd5.0/libstdc++-v3
...
checking for compiler with PCH support..

ps shows:

/home/jsg/src/obj/./gcc/cc1plus -quiet -nostdinc++ -iprefix
/home/jsg/src/obj/gc
c/../lib/gcc/i386-unknown-openbsd5.0/4.7.0/ -isystem
/home/jsg/src/obj/./gcc/inc
lude -isystem /home/jsg/src/obj/./gcc/include-fixed -isystem
/usr/gcc/i386-unkno
wn-openbsd5.0/include -isystem /usr/gcc/i386-unknown-openbsd5.0/sys-include
conf
test.cc -quiet -dumpbase conftest.cc -mtune=i386 -march=i386 -auxbase conftest
-
g -O2 -Werror -Winvalid-pch -Wno-deprecated -o /tmp//ccerRyjL.s

strangely this seems to still happen with --disable-pch and
--enable-languages=c

This seems to be resolved by adding PCH support for OpenBSD.  Without which
builds will fail even if PCH are disabled.

The hang is PR 39618 so closing this as a dup of that bug.
