             Bug #: 13213
           Summary: Building a sanitized Clang with --enable-shared dies
                    with SIGSEGV
           Product: clang
           Version: unspecified
          Platform: Macintosh
        OS/Version: MacOS X
            Status: NEW
          Severity: normal
          Priority: P

Since I've been using more Clang-built tools, I find it useful for debugging to 
use a sanitized Clang.  So I installed compiler-rt, built Clang-3.1 from the 
release branch, and then I built Clang again using that Clang, as follows:

/usr/local/src/llvm/configure --prefix=/usr/local/stow/clang-3.1-asan 
--enable-assertions --enable-expensive-checks --enable-debug-runtime 
--enable-debug-symbols --disable-bootstrap --with-extra-options="-g -O1 
-faddress-sanitizer" --with-extra-ld-options="-g -O1 -faddress-sanitizer" 
CC=/usr/local/stow/clang-3.1/bin/clang 
CXX=/usr/local/stow/clang-3.1/bin/clang++
LD=/usr/local/stow/clang-3.1/bin/clang

This works great.  However, if I add --enable-shared, the build process will 
die with several SIGSEGVs:
