I'm trying to run Python-3.4.0rc3 through Asan.
The package was only mildly difficult to build. The only un-ordinary
part was I had to add some of the sanitizer libraries to LIBS due to
undefined symbols like __asan_report8 when building the Python archive
libpython3.4m.a:
export CC=/usr/local/bin/clang
export CXX=/usr/local/bin/clang++
export CFLAGS="-g3 -fsanitize=address"
export CXXFLAGS="-g3 -fsanitize=address"
export LIBS="/usr/local/lib/clang/3.4/lib/linux/libclang_rt.full-x86_64.a \
/usr/local/lib/clang/3.4/lib/linux/libclang_rt.asan-x86_64.a \
/usr/local/lib/clang/3.4/lib/linux/libclang_rt.san-x86_64.a"
When I run `make test`, I run into some problems (shown below). Does
anyone have an idea why PC is 0x00000000?
Thanks in advance.
