libcompiler-builtins contains DWARF5 debuginfo in 1.62.0 · Issue #98746 · rust-lang/rust (original) (raw)

Building Firefox with rustc 1.62.0 on Linux and running it under valgrind makes valgrind emit the following error:

==31382== Valgrind: debuginfo reader: ensure_valid failed:
==31382== Valgrind:   during call to ML_(img_get)
==31382== Valgrind:   request for range [3275670898, +4) exceeds

==31382==
==31382== Valgrind: debuginfo reader: Possibly corrupted debuginfo file.
==31382== Valgrind: I can't recover.  Giving up.  Sorry.

As of filing, I don't have more information to share yet, but I thought I'd already file it before starting to investigate it next week.
