[MacRuby-devel] Kernel#caller doesn't show directories

[Brian Marick]

I couldn't reproduce it. Vanilla 1.8.6 is still slightly better in that it prints

	from ../../foo.rb:6

whereas a recent 0.7 prints a full path:

	from /Users/marick/src/clients/SES/Tests/preferences/../../foo.rb:6:in `<main>'

Note that backtraces in MacRuby are generated by walking through the stack and sometimes some entries are missing. File/line numbering is retrieved from DWARF metadata but sometimes it's incorrectly compiled. So, bug reports are welcome :-)
