https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D273056 Bug ID: 273056 Summary: devel/gdb: crashes when printing a Rust stack trace Product: Ports & Packages Version: Latest Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: Individual Port(s) Assignee: pizzamig@freebsd.org Reporter: asomers@FreeBSD.org Flags: maintainer-feedback?(pizzamig@freebsd.org) Assignee: pizzamig@freebsd.org The current version of gdb crashes when trying to print the stack trace of a Rust program, if that program was built in debug mode. Rust programs built= in release mode seem to be unaffected. The crash message is: internal-error: inside_main_func: Assertion `block !=3D nullptr' failed Affected gdb versions: 13.1 13.1_2, 13.1_3 Unaffected gdb versions: 12.1_2 12.1_3 Affected OS releases, 13.2-RELEASE, 14.0-CURRENT (today's build) Affected Rust versions: 1.73.0-nightly, 1.68.0, 1.70.0, 1.63.0 Steps to Reproduce =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D 0) Install Rust, if you haven't already, from lang/rust or rustup. 1) git clone --depth=3D1 git@github.com:johalun/sysctl-rs.git 2) cd sysctl-rs 3) cargo build --examples 4) rust-gdb target/debug/examples/value (gdb) b sysctlbyname Function "sysctlbyname" not defined.
