exception on latest rtorrent (commit 4353f1bfa8686a177088822fdebc9909782154f6)

[artifexor]

I've got the following exception: "rtorrent: priority_queue_insert(...) called on an already queued item"

I am using FreeBSD 8.2.

e0e654f fixes a couple of potential issues, however without a proper backtrace I can't determine if the issue above has been fixed.

[artifexor]

Compiled and no exception yet.

For a proper backtrace might this help.

If the examples are right it means that backtrace is automatic at exception and does not need gdb.

[rakshasa]

Several places in the code use exceptions for non-critical error handling, and as such catching them all will not work.

Instead, replace the exception in rak/priority_queue_default.h with an exit call, which gdb will break on automatically.

[artifexor]

Thanks for the hint. I think it's better if a program is self descriptive on errors than need to use gdb. It's not a must but debugging might be easier. I do not start rtorrent from gdb all the time and I had exception that I cannot repeat under gdb so the information was gone.

Yeah, but there's no clean way of providing backtraces from exceptions, so I'll leave it at that for the moment. Fixed the obvious potential causes of this bug so closing for now.
