Bug #8243: ruby-debug-base fails because a function is no longer exported

The ruby-debug-base project (now at https://github.com/cldwalker/debugger )
fails with 2.0 giving an error message like

dyld: lazy symbol binding failed: Symbol not found: _rb_vm_get_sourceline
Referenced from: /usr/local/rvm/gems/ruby-2.0.0-p0@apono/bundler/gems/debugger-e98dc5762a48/lib/ruby_debug.bundle
Expected in: flat namespace

When I reinstate this line in vm_backtrace.c the debugger works fine:

RUBY_FUNC_EXPORTED int rb_vm_get_sourceline(const rb_control_frame_t *cfp);

• File bug08243.patch bug08243.patch added

This patch reinstates the RUBY_FUNC_EXPORTED declaration, including
the comment from 1.9.3 stating that a better interface would be used
in the next version. I don't know of any such interface in the 2.0 code.

Hey Eric -

@ko1 (Koichi Sasada) updated it to use the new Ruby 2 debugging API!

See the debugger2 branch: https://github.com/cldwalker/debugger/compare/master...debugger2
