Hi Gábor, That symbol appears to be defined in compiler-rt/lib/asan/asan_rtl.cc <http://asan_rtl.cc/>, so it should be provided by the asan runtime. Are you sure that the runtime expected by the host compiler is being dynamically loaded here? You can check this using 'ldd' (IIRC) on Linux or 'otool -l' on Darwin. Also, did you take the extra step needed to preload the runtime (LD_PRELOAD/DYLD_INSERT_LIBRARIES)?
