Bug#779785: clang-3.7: -fsanitize doesn't work due to missing ubsan libraries in 3.7 (they were in libclam-common-3.x-dev previously)

[Gregory Stark]

Package: clang-3.7
Version: 1:3.7~svn230892-1
Severity: normal


I get the following when I try to run clang-3.7 with -fsanitize=address,undefined:

configure:3866: checking whether the C compiler works
configure:3888: /usr/bin/clang -g -O2 -fsanitize=address,undefined   conftest.c  >&5
/usr/bin/ld: cannot find /usr/lib/llvm-3.7/bin/../lib/clang/3.7.0/lib/linux/libclang_rt.asan-x86_64.a: No such file or directory
/usr/bin/ld: cannot find /usr/lib/llvm-3.7/bin/../lib/clang/3.7.0/lib/linux/libclang_rt.ubsan-x86_64.a: No such file or directory
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Poking around it seems previous versions of clang these libraries
existed in the libclang-common-3.x-dev package. I'm not sure that
makes sense if they're needed at runtime under normal use so perhaps
they've moved to a different package?

I think I've installed all the relevant 3.7 packages but perhaps
there's a missing dependency and there's a package that isn't uploaded
yet that I'll need for clang to work properly?
