--- Comment #3 from Dan Kegel dank@kegel.com 2010-01-09 21:15:52 --- Also interestingly, if you do cd ~/.wine/drive_c/cygwin/bin wine bash -i the problem does not occur... at least, not until you issue the second command. ./ls works once, but the second time you run it, you get the spewage. Sometimes ^C stops it, but after that, the shell is unstable.
The problem also occurs the same with ash and dash.
