Thanks for reporting it. This is a manifestation of a problem that has been plaguing me since April. This easily reproducible test case allowed me to track down a problem which was causing random handles to be closed. I did notice while debugging this that strace -f hangs on Windows 95. If anyone has any insight into why, I'd be interested in hearing about it. cgf On Sat, Jul 31, 1999 at 03:51:37PM +0900, Kazuhiro Fujieda wrote: >Since the 199-Jul-17 snapshot, commands with redirection of the >standard input, such as `cat < /dev/null' have failed in the >notty mode on Win9x. > >$ cat < /dev/null > 0 0 [main] C:\CYGNUS\CYGWIN~1\H-I586~1\BIN\cat.exe 1002 spawn_guts: wait failed: nwait 3, pid 1002, winpid -231673, Win32 error 6 > 0 4921 [main] cat 1002 spawn_guts: waitbuf[0] 0x1F 0 >20653 25574 [main] cat 1002 spawn_guts: waitbuf[1] 0x12 = 0 >$ > >I can't collect a strace log, because the strace command fails >as the following. > >$ strace -o /tmp/strace.log cat < /dev/nul > 0 0 [main] C:\CYGNUS\CYGWIN~1\H-I586~1\BIN\strace.exe 1005 spawn_guts: wait failed: nwait 3, pid 1005, winpid -232277, Win32 error 6 > 0 5059 [main] strace 1005 spawn_guts: waitbuf[0] 0x1F 0
