Yes, this is fixed with your patches for pr49533.

Thanks.

Yes, if I remove the patch for r174989 then both benchmarks build without
error.

Another thing you might check is to revert the commit
pointed out here: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49533#c5
and see if this makes any difference.

The problems still exist in r176125, although looks like a couple from soplex
went away but a couple new ones for omnetpp showed up.


soplex:

So, looks like a gcc bug after all.  There are four files with a certain group
example.s:.section   
.text._ZN6soplex8SPxBasisD2Ev,"axG",@progbits,_ZN6soplex8SPxBasisD5Ev,comdat
example.s:.section   
.text._ZN6soplex8SPxBasisD0Ev,"axG",@progbits,_ZN6soplex8SPxBasisD5Ev,comdat
soplex.s:.section   
.text._ZN6soplex8SPxBasisD2Ev,"axG",@progbits,_ZN6soplex8SPxBasisD5Ev,comdat
soplex.s:.section   
.text._ZN6soplex8SPxBasisD0Ev,"axG",@progbits,_ZN6soplex8SPxBasisD5Ev,comdat
spxbasis.s:.section   
.text._ZN6soplex8SPxBasisD2Ev,"axG",@progbits,_ZN6soplex8SPxBasisD5Ev,comdat
spxbasis.s:.section   
.text._ZN6soplex8SPxBasisD0Ev,"axG",@progbits,_ZN6soplex8SPxBasisD5Ev,comdat
spxsolver.s:.section   
.text._ZN6soplex8SPxBasisD2Ev,"axG",@progbits,_ZN6soplex8SPxBasisD5Ev,comdat
spxsolver.s:.section   
.text._ZN6soplex8SPxBasisD0Ev,"axG",@progbits,_ZN6soplex8SPxBasisD5Ev,comdat

In each of these files this group contains two sections, with the code for
_ZN6soplex8SPxBasisD0Ev and _ZN6soplex8SPxBasisD2Ev in them.  In just one file,
spsbasis.o, there is an alias for _ZN6soplex8SPxBasisD2Ev.

.weak_ZN6soplex8SPxBasisD1Ev
.set_ZN6soplex8SPxBasisD1Ev,_ZN6soplex8SPxBasisD2Ev

When the group in spsbasis.o is dropped, _ZN6soplex8SPxBasisD1Ev has no proper
definition.

There are some really weird things going on here that make me think this is a
linker bug rather than a gcc bug.  Assigning to myself to save others wasting
time on the PR.
