Hello and thanks for your attention, I am using the newest Cygwin net release (upgraded today by re-running Cygwin Setup to make sure this is not fixed yet). I noticed this problem while writing a long pipeline ending with "| less" and then trying to suspend the processes. When I do this the Cygwin window hangs until I kill the processes in the pipeline with "kill" or Windows Task Manager. The simplest testcase I've managed to find is:
cat README | less # press ^Z immediately, hangs. Scroll to the bottom and works This one always fails, naturally... yes | less I can reproduce the former case with any text file that is at least 16k long, probably the true value is the number of bytes "less" reads from a pipe when it starts, and this bug happens if you suspend a pipeline where a writer is currently writing to a pipe and blocked because reader hasn't read the data yet. Can't suggest any fixes though. If you have any questions, please Cc: to me also because I'm not on the list.
