[Bug-ddrescue] Ddrescue freezes on Mac OS X

[Kristofer Widholm]

See below terminal output. There were no compile errors when I built
ddrescue. When I run fs_usage, I see file system activity at all going on.
The process just hangs at 0%. There's obviously nothing being done, but
there's also nothing being generated in the error log. Something is causing
ddrescue to choke.


 $ ddrescue -v /dev/disk1s6 bhm.dmg volume_rescue.log
