Bug#729049: clang-3.3: Failed to build 32-bit program with undefined behavior sanitizer on 64-bit host

[Turo Lamminen]

Package: clang-3.3
Version: 1:3.3-12
Severity: normal

I'm trying to build a 32-bit program with undefined behavior sanitizer
on a 64-bit host. Linker fails with this error:

/usr/bin/ld: cannot find /usr/bin/../lib/clang/3.3/lib/linux/libclang_rt.san-i386.a: No such file or directory

The 64-bit libraries are in package libclang-common-3.3-dev but it's not
possible to install the 32-bit package simultaneously, aptitude says:
 libclang-common-3.3-dev : Conflicts: libclang-common-3.3-dev:i386 but 1:3.3-12 is to be installed.
 libclang-common-3.3-dev:i386 : Conflicts: libclang-common-3.3-dev but 1:3.3-12 is installed.

Building 32-bit programs without the sanitizer works fine.
