Bug #5614
closedProc#source_location & #inspect shows wrong line number when chained
Description
When procs are chained, the line number for each proc is mis-calculated to be the 1st proc's line-number.
Eg.
class Foo
def bar(&blk)
pp blk.source_location
self
end
end
Foo.new.bar do
puts 'b1'
end.bar do
puts 'b2'
end
The 1st & 2nd procs show the same line number, when they shouldn't.
Though i listed the target version as 1.9.2, this behaviour is consistent for all versions of mri.

It may not a bug but a specification. A block returns the number of a line in which the block is defined for its "source_location." When you use procs instead of blocks, it returns the values you expected.
Code:
1 require 'pp'
2 class Foo
3 def bar(&blk)
4 pp blk.source_location
5 self
6 end
7 end
8
9 Foo.new.bar(&proc{
10 puts 'b1'
11 }).bar(&proc{
12 puts 'b2'
13 })
Result:
$ ruby procs.rb
["procs.rb", 9]
["procs.rb", 11]
