c++_shared crashed. c++_static also crashed. Both have libc++ code
landing in the final .so — one as a NEEDED dynamic lib, the other
bundled statically. So the trigger isn't the NEEDED entry specifically,
it's libc++ being present in any form.
cpp_smoke.cpp is just 'extern "C" int wzp_cpp_hello() { return 42; }'
with zero C++ features used, so we can drop cpp_link_stdlib completely
and the compile still succeeds. No libc++ .a or .so referenced at all.
If this crashes: the trigger is cc::Build::new().cpp(true) switching
rustc's final linker driver from clang to clang++ (which pulls in
different default libraries).
If this launches: the trigger is libc++'s own static initializers or
the libc++ code itself doing something that breaks our .so at dlopen
time, and we have a path forward — C++ code that doesn't need libc++
(e.g., a thin C++ bridge to Oboe that uses only POD types at the
boundary, with all the STL stuff confined to Oboe's own compilation
unit which would still need libc++...). More likely we still need a
C-only audio interface like raw AAudio via the ndk Rust crate.
