New issue 367 by [email protected]: sanitizer prevents linking, tons of
undefined references
https://code.google.com/p/address-sanitizer/issues/detail?id=367
What steps will reproduce the problem?
1. write a trivial 6-line C++ program (attached).
2. Compile it, and try to link resulting object file.
for example:
clang++-mp-3.5 -fsanitize=undefined -std=c++11 -o t t.cpp -lc++
3. Observe the failure and error messages.
What is the expected output? What do you see instead?
Expected output: successful creation of an executable file.
What I see instead - a bunch of error like:
$ /opt/local/bin/clang++-mp-3.5 -fsanitize=undefined -std=c++11 -o t t.cpp
-lc++
