Top frame from interpreter gets wrong filename #5849
Description
Example code:
required.rb:
puts caller(0)test.rb:
require "./required.rb"Output on JIT and interpreter:
[] ~/projects/jruby $ jruby test.rb
/Users/headius/projects/jruby/required.rb:1:in `<main>'
/Users/headius/projects/jruby/lib/ruby/stdlib/rubygems/core_ext/kernel_require.rb:1:in `require'
/Users/headius/projects/jruby/lib/ruby/stdlib/rubygems/core_ext/kernel_require.rb:1:in `(root)'
test.rb:1:in `<main>'
[] ~/projects/jruby $ jruby -X-C test.rb
/Users/headius/projects/jruby/required.rb:1:in `<main>'
/Users/headius/projects/jruby/lib/ruby/stdlib/rubygems/core_ext/kernel_require.rb:1:in `require'
/Users/headius/projects/jruby/lib/ruby/stdlib/rubygems/core_ext/kernel_require.rb:1:in `(root)'
/Users/headius/projects/jruby/lib/ruby/stdlib/rubygems/core_ext/kernel_require.rb:54:in `<main>'
I'm not sure why that top frame is getting screwed up. If we change the contents of required.rb to raise, the trace is also incorrect:
[] ~/projects/jruby $ jruby -Xbacktrace.style=mri test.rb
/Users/headius/projects/jruby/required.rb:1:in `<main>': unhandled exception
from org/jruby/RubyKernel.java:987:in `require'
from /Users/headius/projects/jruby/lib/ruby/stdlib/rubygems/core_ext/kernel_require.rb:1:in `(root)'
from test.rb:1:in `<main>'
[] ~/projects/jruby $ jruby -Xbacktrace.style=mri -X-C test.rb
/Users/headius/projects/jruby/required.rb:1:in `<main>': unhandled exception
from org/jruby/RubyKernel.java:987:in `require'
from /Users/headius/projects/jruby/lib/ruby/stdlib/rubygems/core_ext/kernel_require.rb:1:in `(root)'
from /Users/headius/projects/jruby/lib/ruby/stdlib/rubygems/core_ext/kernel_require.rb:54:in `<main>'
This is not specific to the MRI backtrace; the JRuby format also shows the problem. It seems like a top-level backtrace element is getting stomped on.
