ARM Fiber bug

[egillet]

I just try the 0.8.2 version with a Crystal 0.23.1 [e2a1389e8] LLVM 3.8.
There is a bug that doesn't allow sqlite to run in a spawned Fiber (which is annoying if you try to run Kemal e.g.)

The bug is easy to reproduce:
require "sqlite3"

spawn do
DB.open "sqlite3://%3Amemory%3A" do |db|
db.exec "CREATE TABLE IF NOT EXISTS contacts (name string, age integer)"
puts "=== count is #{db.scalar "select count(*) from contacts"}"
end
end
sleep 1.seconds

The execution gives:

---inside #step : #SQLite3::Statement:0x412d20 sql select count(*) from contacts
Unhandled exception in spawn:
database disk image is malformed (SQLite3::Exception)

Hi, Thanks for report this issue

Why ARM, did you try other architectures? It, just happen on crystal-sqlite3 ?

I used a raspberry 2 and a Odroid-UX4, both 32 bits armhf. The pg packet is working well.

Any updates on this? I am having the same issue with Crystal 0.34.0 and the latest version of crystal-sqlite3.
