Some checks failed
Build Release Binaries / build-amd64 (push) Failing after 3m53s
Last bisection step. cpp/cpp_smoke.cpp reduced to a single extern 'C'
function that returns 42. No #include, no std::atomic, no std::mutex,
no std::thread. Only C++ things remaining are:
- cc::Build::new().cpp(true) in build.rs (C++ mode compile)
- cpp_link_stdlib('c++_shared') emitting -lc++_shared
If this still crashes with the same __init_tcb+4 / pthread_create
stack, we've conclusively proven the trigger is NOT any C++ code
that ends up in the final .so (everything gets dead-stripped
anyway because Rust never references wzp_cpp_hello). The trigger
must be either:
a) cargo:rustc-link-lib=c++_shared (adds NEEDED entry for
libc++_shared.so in the .so's dynamic table, causing the
dynamic linker to load libc++_shared.so at dlopen() time
alongside our .so), or
b) Some interaction between cpp(true) mode and the rest of the
build pipeline (toolchain flags, symbol visibility, etc.)
After this build we stop and write an incident report for the
WarzonePhone Tauri Android rewrite bisection so far.
