The command sequence that led to that was:

apk add git
git clone https://github.com/atsign-foundation/noports
cd noports/packages/dart/sshnoports/
dart pub get --enforce-lockfile
dart run build_runner build --delete-conflicting-outputs

The same sequence (and more) runs just fine on x64.

Summary: The user is experiencing a crash with the error "Illegal instruction(4)" when running dart run build_runner build on a StarFive VisionFive 2 RISC-V board using the dart-musl image. The crash occurs during JSON decoding, potentially indicating an issue with the RISC-V architecture support in the Dart runtime.

The build command works for me on Debian RISCV64 with the official build.

I'm not able to run the musl version on my RV device because of some docker network issue. Can you run this under gdb and disassemble around the bad address?

gdb --args dart run build_runner build --delete-conflicting-outputs
(gdb) run
...
si_signo=Illegal instruction(4), si_code=ILL_ILLOPC(1), si_addr=0x34d22439c6
...
(gdb) disassemble 0x00000034d22439b0,+100

Or run with the VM's disassembler and search backwords for the address?

dart --disassemble --isolate-log-filter=dartdev run build_runner build --delete-conflicting-outputs

For completeness I tried the same sequence on my Ubuntu (and hence glibc) based build image and that also crashes (in this case at dart pub get):

I'd note that the same sequence (and more) runs inside of Docker buildx (hence using QEMU) every time we release binaries, and whilst it hangs far too frequently it doesn't crash in this manner. Given the recent differential fuzzing that targeted both QEMU and the JH7110 SoC in the VisionFive 2 (amongst others) I'm surprised by the differing behaviours I'm seeing here.

and for further completeness I ran the sequence without Docker (just Ubuntu 24.04.1 on the StarFive VisionFive 2) and no crash. So maybe Docker is the underlying cause?

Hm, the instructions seems reasonable. I wonder if this is something like a previous issue seen with Docker with instruction mapping.

Can you try running with the background compiler disabled? If this succeeds, it could be something related to instruction synchronization.

Good call @rmacnak-google dart --no-background-compilation run build_runner build --delete-conflicting-outputs does indeed succeed (this is on the original setup using dart-musl):

I recall that previous issue (and especially @mraleph gripes about not being able to reproduce it due to not being allowed Docker Desktop) as my colleague @cconstab hit a similar issue with arm that features later in the thread.

The docker --version in use here is:

Docker version 24.0.7, build 24.0.7-0ubuntu4.1
