Bug #: 53614
Summary: g++ undefined symbols static const data members
conditional assignment
Classification: Unclassified
Product: gcc
Version: 4.4.6
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: cam888e...@yahoo.com

output of -save-temps
I wanted to attach a 2nd file, main.ii. Also a 3rd file, Foo.cc.
Looks like this only allows 1 attachment. I will try to send later.
main.ii should let you duplicate ld error undefined symbols.
Foo.cc if you wish to verify correctness using
-DWORKAROUND, otherwise please ignore it. Thanks.
% echo ; g++ -v -save-temps -m64 -c Foo.cc ; echo ; g++ -v -save-temps -m64
-odefineMe main.cc Foo.o
