next causes Integer#times to lose count
Reported by Adam Shelly | February 27th, 2008 @ 12:22 AM | in 1.0 preview
a 'next' in the middle of an integer#times loop causes the loop execute at least one extra time.
ads@andLinux:~/rubinius/code/work$ more nextbug.rb
a = []
2.times do
a << 1
if a.size==1
next
end
a << 2
end
p a
p a == [1,1,2]
ads@andLinux:~/rubinius/code/work$ ruby nextbug.rb
[1, 1, 2]
true
ads@andLinux:~/rubinius/code/work$ rbx nextbug.rb
[1, 1, 2, 1, 2]
false

Adding a block argument (2.times do |z|, for example) causes this code to behave properly.
That means it is due to the compiler plugin that inlines Fixnum#times code.
Specifically, class CompilerInlining in lib/compiler/plugins.rb

The part of the plugin that was failing for this ticket has been fixed. However, the plugin is currently disabled for now awaiting fixes to handling break. A bunch of specs have been added to catch regressions once the plugin is re-enabled.
Resolving for now. Reopen if necessary.
