Bug #20296
Updated by MaxLap (Maxime Lapointe) 11 months ago
Happens in Ruby 3.2.2, 3.2.3 and 3.3.0 (didn't test others).
Add this to a file and execute it as-is:
```
3.times { Complex(:sym, exception: false) }
puts "hi"
```
The output will be:
```
$ ruby local2.rb
hi
local2.rb:1:in `Complex': can't convert Symbol Array into Complex (TypeError)
3.times { Complex(:sym, Complex([], exception: false) }
^^^^^^^^^^^^^^^^^^^^^^ ^^^^^^^^^^^^^^^^^^^^
from local2.rb:1:in `block in <main>'
from local2.rb:1:in `times'
from local2.rb:1:in `<main>'
local2.rb:1:in `Complex': can't convert Symbol Array into Complex (TypeError)
3.times { Complex(:sym, Complex([], exception: false) }
^^^^^^^^^^^^^^^^^^^^^^ ^^^^^^^^^^^^^^^^^^^^
from local2.rb:1:in `block in <main>'
from local2.rb:1:in `times'
from local2.rb:1:in `<main>'
local2.rb:1:in `Complex': can't convert Symbol Array into Complex (TypeError)
3.times { Complex(:sym, Complex([], exception: false) }
^^^^^^^^^^^^^^^^^^^^^^ ^^^^^^^^^^^^^^^^^^^^
from local2.rb:1:in `block in <main>'
from local2.rb:1:in `times'
from local2.rb:1:in `<main>'
```
So the exception is still reported (instead of being swallow), but the puts, which is after, had the time to execute first. I can even put a `sleep()` in between and the exceptions are still reported after the puts.
In a IRB, there is no exception at all and everything seems to work as expected.
Happens if I pass in an Array too. Doesn't seem to happen with bad strings.
There is also a quadratic behavior somewhere in there. Running the code in an IRB (which doesn't show exceptions), if you double the number of `times` in the loop, it takes 4x as long. This is probably related...
