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) 0x72eb4: *CallStack::unwind:Array(Pointer(Void)) at /home/pi/Projects/crystal/src/float/printer/cached_powers.cr 1:1 0xd7cf0: move_next at /home/pi/Projects/CrystalThinking/lib/sqlite3/src/sqlite3/result_set.cr 20:7 0xce484: scalar at /home/pi/Projects/CrystalThinking/lib/db/src/db/statement.cr 39:13 0xcec04: scalar at /home/pi/Projects/CrystalThinking/lib/db/src/db/pool_statement.cr 44:30 0xc5268: scalar at /home/pi/Projects/CrystalThinking/lib/db/src/db/query_methods.cr 223:7 0x6e584: ~procProc(Nil) at /home/pi/Projects/crystal/src/time/format/pattern.cr 1:1 0x83260: run at /home/pi/Projects/crystal/src/fiber.cr 255:3 0x6d834: ~proc2Proc(Fiber, (IO::FileDescriptor | Nil)) at /home/pi/Projects/crystal/src/concurrent.cr 61:3

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.
