 Leonardo Santiago | Guess what? Setting ulimit -s unlimited made it work. | 16:29:35 |
| Leonardo Santiago | It was an uncaught stack overflow. | 16:29:45 |
| Leonardo Santiago | Didn't even occur to me until now. | 16:29:57 |

| Leonardo Santiago | @roberth how does nix circunvent this issue in their main binary? I see I can try leveraging ld's -z stack_size=X but it only seems to work if you set it in the entry point elf binary, which I can't do as it's python! I didn't want to bleed this problem elsewhere, like force people to set ulimit -s unlimited, but I don't see many other ways around it, and surely nix has had to deal with this; though it is the elf entry point. Any tips or hints? | 13:21:26 |
| Leonardo Santiago | There's the possiblity of spawning a new thread with an increased stack size, but that adds the context switching overhead to every nix evaluation, which is something I'd like to avoid if possible. | 13:22:44 |

| Leonardo Santiago | There's also the possibility of using setrlimit to increase the process's own stack size, that seems to me like the most graceful solution | 14:09:58 |
| Leonardo Santiago | And indeed, that seems the solution that nix's binary uses, src/nix/main.cc calls nix::setStackSize(64MB) which internally calls setrlimit with that value. Awesome to know, most likely I'll try going down this route. | 14:12:10 |

| Leonardo Santiago | I notice I may be bringing all the stupid problems and ideas to the chat, but would it be possible to static link against the nix C libraries? | 15:55:05 |
