I can also reproduce it under cygwin 1.7, and further clarified that it is the second cat that is failing: $ sleep 100 | cat ^Z $ bg cat: -: Bad address I'm not quite sure how to strace this, since you can't use ^Z to suspend an active strace. But my guess is that there is a bug in cygwin1.dll pipe handling code, such that it dereferences bad memory when resuming execution of a read from a pipe after a SIGSTOP; cat is just reporting the EFAULT from a failed read() call. -- Eric Blake volunteer cygwin coreutils maintainer -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
