Hash check raises SIGBUS from libcrypto.so

[esainane]

Description:

After opening rtorrent, and opening a particular closed torrent to resume a hash recheck, rtorrent will crash about 4% through the hash check with SIGBUS.

Terminal output:

Caught SIGBUS, dumping stack:

Duplicate check:

Going through open and closed issues referencing SIGBUS, I believe this is a new issue:

• 28 was resolved by setting -O2. When building from source, -O2 was (automatically) used, and the problem persists.

• 39 has the stack trace finger libtorrent rather than libcrypto, and the probable fix (a015c336) has been included in libtorrent for a very long time.

• 90 doesn't describe my issue, rtorrent does not crash immediately.

• 175 describes an edge case where the disk is too full. I have 55G spare on the destination partition, and 28G spare on the root partition, each of which would be enough several times over.

• 238 describes an issue with the underlying filesystem. I do not have any relevant warnings or errors in dmesg, and other torrents work correctly.

• 240 refers to the full disk case.

• 248 and #356 refer to BTRFS; neither my root nor my destination partitions are BTRFS.

• 393 refers to the full disk case.

• 417 may be relevant since libcrypto is fingered in the stack trace, but there isn't enough information in the issue to be sure either way.

• 526 fingers libtorrent rather than libcrypto.

Reproducibly tested with:

• Debian packages libtorrent19/testing 0.13.6-1.1 amd64, rtorrent/testing 0.9.6-2 amd64
• Compiled from source using current libtorrent master rakshasa/libtorrent@c167c5a9, and rtorrent commit 10ce6864. I cannot test with the current rtorrent master, as the current rtorrent master (from the commit after 10ce6864, 7902c614 onward) uses LOG_CONNECTION_FILTER introduced in the libtorrent feature-bind branch, which raises the issue described in #327.

Please let me know if there is anything I can do to help.

[chros73]

After opening rtorrent, and opening a particular closed torrent to resume a hash recheck ...

Can you describe the steps to reproduce this?

[2600box]

I get this issue constantly on debian 8. I have plenty of free disk space. I have tried with debian deb and building from feature-bind. same result.

problem still exist. caused by bad sector on disk in my case unfortunately i have already remapped bad sector so can do additional checks.
