Bug #: 51832
Summary: [4.7 regression] Rev.182970 causes LTO link errors
(multiple definitions of allocator_traits)
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: markus@trippelsdorf.de
Rev.182970 causes LTO link errors because of multiple definitions that all
start with '_ZNSt16allocator_traits', e.g.:
c++ -o elfhack -fno-rtti -Wall -Wpointer-arith -Woverloaded-virtual -Wsynth
-Wno-ctor-dtor-privacy -Wno-non-virtual-dtor -Wcast-align -Wno-invalid-offsetof
-Wno-variadic-macros -Werror=return-type -Wno-long-long -march=native -flto=4
-fno-fat-lto-objects -Wno-delete-non-virtual-dtor -fno-strict-aliasing
-std=gnu++0x -pthread -ffunction-sections -pipe -fexceptions -DNDEBUG

That symbol is an extra-name alias for
std::allocator_traits<std::allocator<int> >::__construct_helper<int,
int>::value
created by mangle_decl for forward ABI compatibility.
But I can't reproduce the bug; that variable isn't emitted at all when I
compile the reduced testcase with r183124.

Hmm, that's strange.
I've updated binutils and gcc just to double-check and it still fails:
(Please note that foo.cpp occurs _twice_ below)

I still can't reproduce this on x86_64-pc-linux-gnu. I notice that you have a
lot of configure flags in your gcc -v output; mine is just
/home/jason/src/trunk/configure -v --with-mpfr=/opt/cfarm/mpfr
--with-gmp=/opt/cfarm/gmp --with-mpc=/opt/cfarm/mpc
--with-libelf=/opt/cfarm/libelf --enable-languages=all,obj-c++
--enable-checking
Can you try rebuilding the compiler with different configure flags and see if
one of them is causing this difference? I tried building the compiler with all
your configure flags, but it seems to result in a broken stage1 compiler for
me.

Even the most minimal config fails on my machine:
gcc_build_dir % ../gcc/configure --disable-multilib --enable-checking
--enable-languages=c,c++
gcc_build_dir % make -j4
My gcc git clone is clean:
gcc % git status
# On branch master
nothing to commit (working directory clean)
Can anybody else except Jason reproduce this issue?

It does happen with the gcc I built yesterday on an up-to-date debian testing
box (using the testcase from comment #2). Just so you know you're not the only
one...

I can't reproduce it with the reduced testcase but _can_ reproduce it with
test.ii test2.ii from the attachment.

It does not reproduce when not using the linker plugin though and I am
using a linker that uses the v2 interface with the fancy COMDAT support
(the 2.22 release).

libxul link error log
BTW I've first observed this bug while building
a PGO-LTO Firefox. The errors of the final libxul
link are attached (unrelated warnings have been deleted).
As you can see there are ~350 (closely related) errors altogether.

What binutils version are you running on both machines?
(is PREVAILING_DEF_IRONLY_EXP already supported?)
Is gcc20 a 64bit machine running a 64bit gcc?
