conradin laux (Dec 19 2024 at 18:09): conradin laux (Dec 19 2024 at 18:09):I get a weird segfault when reading files larger than 997 bytes. In the reproducible case below, all of the main function is run, but the process crashes.
python3 -c "print('X' * 996)" > file
app [main] { pf: platform "https://github.com/roc-lang/basic-cli/releases/download/0.17.0/lZFLstMUCUvd5bjnnpYromZJXkQUrdhbva4xdBInicE.tar.br" }
import pf.File
parse = \s ->
s
|> Str.splitOn "\n"
|> List.dropFirst 1
|> List.dropIf Str.isEmpty
main =
dbg (File.readUtf8! "file" |> parse)
Task.ok {}
❯ roc build ./tmp.roc

is this on linux (asking cause works just fine on m1 mac)?
Brendan Hansknecht (Dec 19 2024 at 18:16):Also, can you test with --linker legacy
conradin laux (Dec 19 2024 at 18:27):Yes, linux 6.12.4; --linker legacyfixes the problem
Brendan Hansknecht (Dec 19 2024 at 18:49):interesting. I wonder what is going wrong with the surgical linker here (or with the platform built for the surgical linker)
Anton (Dec 20 2024 at 09:59):Can you file an issue on the basic-cli repo @conradin laux?
