• Bug#1104731: clang-19: Stack dump on a specific emscripten test

    From =?utf-8?b?SsOpcsOpbXkgTGFs?=@21:1/5 to All on Mon May 5 13:40:03 2025
    Package: clang-19
    Version: 1:19.1.7-3
    Severity: normal

    Hi,

    one of emscripten tests is failing with:

    PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace, preprocessed source, and associated run script.
    Stack dump:
    0. Program arguments: /usr/bin/clang-19 -target wasm32-unknown-emscripten -fignore-exceptions -mllvm -combiner-global-alias-analysis=false -mllvm -enable-emscripten-sjlj -mllvm -disable-lsr --sysroot=/build/reproducible-path/emscripten-3.1.69+dfsg/debian/

    Should I hope to see this fixed in llvm,
    or should I just consider that test to not be compatible with llvm-19 ?

    Is it worth collecting the diagnostics ?
