where the bl 0 causes a seg fault.
I'll check x86_64, but currently don't have that setup, so it'll take me a little bit of time to check.

<pre wrap="">
Those command line options don't exist on trunk.
The following works for me:
$ clang++ -O0 weakImpl.cpp -o weakImpl.o -c
$ clang++ -O1 -o weakMainO1.exe -flto -static weakMain.cpp weakImpl.o
Do you also see the issue with x86_64?
