Sanitizer work with --enable-stdcxx-compat and gcc >= 4 .5
When building with --enable-stdcxx-compat (required on the linux slaves with Clang it seems), I get the following error when building with AddressSanitizer support: TEST-UNEXPECTED-FAIL | | We don't want these libstdc++ symbols to be used: 0000000000000000 DF *UND* 0000000000000000 GLIBCXX_3.4.14 _ZNSsC1EOSs 0000000000000000 DF *UND* 0000000000000000 GLIBCXX_3.4.14 _ZNSsaSEOSs make: *** [ssltunnel] Error 1 make: *** Deleting file `ssltunnel' make: *** [libs] Error 2 make: Leaving directory `/builds/slave/try-lnx64-dbg/build/obj-firefox/testing/mochitest/ssltunnel' Glandium explained me that this is due to stdc++compat.cpp being opt-in. However, the AddressSanitizer runtime library itself is written in C++ and seems to pull in dependencies that make it a requirement to have stdc++compat.cpp everywhere.
Try build: https://tbpl.mozilla.org/?tree=Try&rev=735716659700 (STDCXX_COMPAT is only enabled on linux and mac) This ensures we don't have any more surprise with random binaries requiring stdc++compat to be linked to it. And linking as a static library ensures that it's actually not included unless it's used (since the linker discards unused object files from static libraries)
Missing an ifdef in build/unix/Makefile.in
