[Bug bootstrap/49246] bootstrap comparison failure with 174455 on OpenBSD


http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49246

--- Comment #2 from Jonathan Gray <jsg at openbsd dot org> 2011-08-09 00:16:20 UTC ---
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
