## Summary Executing the exact instructions from the [rtems user manual](https://docs.rtems.org/branches/master/user/rust/bare-metal.html#bare-metal-rust-with-rtems) results in a `hello_rtems_sparc.exe` executable which crashes when executed. Currently, the output looks like: ``` + rtems-run --rtems-bsp=leon3-sis hello_rtems_sparc.exe RTEMS Testing - Run, 6.0.not_released Command Line: /opt/rtems/6/bin/rtems-run --rtems-bsp=leon3-sis hello_rtems_sparc.exe Host: Linux 134940171c14 5.14.21-150500.55.68-default #1 SMP PREEMPT_DYNAMIC Wed Jun 5 21:39:05 UTC 2024 (40e256a) x86_64 Python: 3.12.3 (main, Sep 11 2024, 14:17:37) [GCC 13.2.0] Host: Linux-5.14.21-150500.55.68-default-x86_64-with-glibc2.39 (Linux 134940171c14 5.14.21-150500.55.68-default #1 SMP PREEMPT_DYNAMIC Wed Jun 5 21:39:05 UTC 2024 (40e256a) x86_64 x86_64) SIS - SPARC/RISCV instruction simulator 2.30, copyright Jiri Gaisler 2020 Bug-reports to [email protected] LEON3 emulation enabled, 4 cpus online, delta 50 clocks Loaded hello_rtems_sparc.exe, entry 0x40000000 *** FATAL *** fatal source: 9 (RTEMS_FATAL_SOURCE_EXCEPTION) CPU: 0 unexpected trap 133 PSR = 0xf3401fc0 PC = 0x4000adc8 nPC = 0x4000adcc WIM = 0x00000040 Y = 0x00000000 g0 = 0x00000000 g1 = 0x4000b32c g2 = 0x00010009 g3 = 0x0001004b g4 = 0x00000000 g5 = 0x00000000 g6 = 0x40026600 g7 = 0x00000000 [more register dumps] ``` The first known buggy build was: | | Version/Commmit | | ------ | ------ | |Date: |2024-10-10T09:56:41+02:00 | |rtems-docs: |7817d7a306cb4627b1208be84c33c4d9b1b2201f | |rtems-source-builder: |989ec6342f410f21e6585e4828a4c5f4f8da5e83 | |rtems: |bd9f5c1eb07ec245576abb93d3bc54618be1fb94 | |cargo: |1.81.0 (2dbb1af80 2024-08-20) | |rustc: |1.83.0-nightly (eb4e23467 2024-10-09) | The last known good build was: | | Version/Commmit | | ------ | ------ | |Date: |2024-10-09T02:33:07+02:00 | |rtems-docs: |7817d7a306cb4627b1208be84c33c4d9b1b2201f| |rtems-source-builder: |8c8156d2133a08d5b93de33828ae1e7009f49974 | |rtems: |bd9f5c1eb07ec245576abb93d3bc54618be1fb94 | |cargo: |1.81.0 (2dbb1af80 2024-08-20) | |rustc: |1.83.0-nightly (3ae715c8c 2024-10-07) | I had the CI re-run with the *rtems, rtems-source-builder, rtems-docs* git commits from the last good build – resulting in the same crash. Hence, I assume this is a new bug Rust *nigthly*. By the way, the build of hello world for Risc V (which is also part of the RTEMS user manual instructions) is not affected and works fine. It uses the *standard* `rustc` and not the *nightly* one. The last bug of this type #32 was just closed by the Rust community on Sunday (with a lot of labor) and this new issue pops up on Thursday ... ## Steps to reproduce Follow the instructions in [Bare Metal Rust with RTEMS](https://docs.rtems.org/branches/master/user/rust/bare-metal.html#bare-metal-rust-with-rtems) ### Pre-set options -- View it on GitLab: https://gitlab.rtems.org/rtems/docs/rtems-docs/-/issues/37 You're receiving this email because of your account on gitlab.rtems.org.
