It seems that the Rust MP4 parser is run a new Rust-created thread in order to catch panics. Once we introduce Rust code that intermingles with C++ more, it won't be practical to put all potentially panicing Rust code into dedicated threads.
Can we install a custom panic function that detects whether it's running on a Rust-created thread and performs a normal Rust panic if it is and performs a MOZ_CRASH if not (i.e. if it is on a non-Rust-created thread)? -- Henri Sivonen hsivo...@hsivonen.fi https://hsivonen.fi/ _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
