Subject: ruby1.8: Exceptions in threads all get converted to a TypeError

Package: ruby1.8
Version: 1.8.2-9
Severity: normal
Tags: sid

When "abort_on_exception" for Thread is set to true, exceptions get
transformed to a TypeError with the same message everytime regardless what
the original exception was. This makes it very hard to debug programs
using threads. This problems only occurs with Ruby 1.8.3 (or this is the
version ruby1.8 in sid reports):

In sarge:
---
irb(main):001:0> Thread.abort_on_exception = true
=> true
irb(main):002:0> Thread.new { p foo }
(irb):2:in `irb_binding': undefined local variable or method `foo' for main:Object (NameError)
        from (irb):2:in `initialize'
        from (irb):2:in `new'
        [...]
---

In sid:
---
irb(main):001:0> Thread.abort_on_exception = true
=> true
irb(main):002:0> Thread.new { p foo }
TypeError: no implicit conversion from nil to integer
        from (irb):2:in `initialize'
        from (irb):2
irb(main):003:0> Thread.new { 10 / 0 }
TypeError: no implicit conversion from nil to integer
        from (irb):3:in `initialize'
        from (irb):3
---

Greetings,

Paul
